info : setting up Back To My Mac through a TG712 modem-router

Question :

How do I setup my Thomson TG712 modem-router to allow me to use the the Back To My Mac function of my Macs ?

Answer :

Here’s how to turn on Back To My Mac when you have a TG712 modem-router :

– on your Mac, go to Apple —> System Preferences —> iCloud

– then put a check mark at “Back To My Mac” to turn the service on

– if there’s a “More…”-botton click it, just for your information ; if a warning is listed, read it, keep it in mind, and don’t bother…

– then open Safari (or any other internet browser) on your Mac, and type the web based control panel’s IP-address of your router-modem as the URL ; for the TG712 router- modem, the IP-address is

– in the web based control panel, go to “Toolbox” (in the menu on the left) –> “Games & Apps Sharing” (in the menu on the left)

– then in the middle of the page, at the bottom, from the “Choose a task…” list, click on “Add a game or application to a local networking device” (the first link in the list)

– in the page that opens, put check marks both at “Use UPnP:” and “Use extended security:”

– and set the “Game or App”-dial (the one that is initially at “ABC (Another Bittorent Client)”) to “Back To My Mac”

– set the “Device”-dial to your Mac (which is the Mac that you would like to use with Back To My Mac, so probably your Mac-server or desktop-Mac)

– just to be able to trace possible errors, put a check mark at “Logging”

– then click on the “Add”-button

– wait for the router-modem to restart

– logout by closing the browser-page with the web based control panel on it

Now you should be able to log into your (home) Mac, when being at a remote location (if there’s internet connection there…)

tip : quickly switching your AirPort Guest Network ON or OFF from your iPhone, iPad or Mac

Question :

I have an AirPort Guest Network setup on my WiFi network, but most of the time I don’t need it… is there a way to temporarily switch it OFF ?

Answer :

Yes, you can do that quickly using the AirPort Utility app on your iPhone, iPad or Mac.

Here’s how to :

– make sure you have the AirPort Utility app installed (on your Mac it’s pre-installed), for your iPhone or iPad, you can download it here :

– open the AirPort Utility

– click on the picture of your AirPort Base Station (or Time Capsule)

– if you’re asked to type your password, type the password you’ve set on access of your AirPort Base Station hardware (note : that is something else than your WiFi / AirPort password)

– in the page (on your Mac it’s a popup window) that opens, click the EDIT-button

– on the page that opens in iOS, select your Guest Network and on the next page switch Guest Network OFF and click on DONE, then DONE again on the next page and UPDATE in the popup panel

– on your Mac you should select the “Wireless”-tab and uncheck the check mark in front of Guest Network and click UPDATE

– then wait for the AirPort Base Station (or Time Capsule) to restart, and then exit the AirPort Utility app

– Done !

To switch the Guest Network back on, just use the same procedure, but put the Guest Network to ON (in stead of OFF).

fixed : bypassing AirPort Guest Network conflict with TG712 router-modem

Question :

I’m trying to setup an AirPort Guest Network on my wireless network, so I need to set my AirPort Base Station (or Time Capsule) to “DHCP and NAT”-mode, but I have a TG712 router-modem that doesn’t have any option to turn DHCP off, so I get a “Double NAT”-error. Even my ISP’s helpdesk say they can’t help me on this one… What can I do ?

Answer :

If your router-modem can’t turn off it’s DHCP-server function, you should preferably set your AirPort Base Station (or Time Capsule) to “Bridged Mode”to get the easiest setup and the best performance. On the other hand : if your AirPort Base Station of the 3rd generation or newer (or it is a Time Capsule), then AirPort’s Guest Network mode is the easiest and safest way to give internet access to your visitors (temporary) internet-access, without giving them access to my private wireless/ethernet network. Even though your internet connection performance may slightly degrade, you can get both of these worlds combined. Here’s how :

– first, make sure that your router-modem is on, and that only one ethernet/UTP port is connected ; the ethernet/UTP-cable from that one port should go directly into your AirPort Base Station’s WAN-port and all your WiFi and Ethernet/UTP equipment should connect to the AirPort Base Station, not to the router-modem

– then open AirPort Utility (version 6 or newer – settings needed in previous versions of AirPort Utility are similar, but the user interface for setting it up is completely different) 

– click on the (large) AirPort Base Station icon

– in the popup window that opens, click on the EDIT-button

– now you’ll get the pulldown window where you can set your preferences

– select the “Internet”-tab

– set “Connect Using:” to “Static”

– if things were on “DHCP” before,  leave the rest as is… else go to “Router Address:” and type your modem-router’s IP-address (for the TG712 that would be, then at “IPv4 Address:” type an IP-address that only differs on the last digit (so or something like it) and set “Subnet Mask:” to ; at “DNS Servers:” type the IP-addresses of the Primary and Secondary DNS that your ISP has given you (if you can’t find those, you should be able to use Google’s Public DNSes : and

– select the “Network”-tab

– set “Router Mode:” to “DHCP and NAT”

– then select the “Wireless”-tab

– there, you should put a check mark at “Enable Guest Netwok:” and give your future Guest Network a distinguishable name

– set “Guest Network Security:” to “WPA/WPA2 Personal”

– then, at “Guest Network Password:” type a password that you can easily remember, but is not like any other password you’ve ever used before

– at “Verify Password:” retype that same password

– then select the “Network”-tab again

– there, you should click on the “Network Options…”-button

– in the pulldown panel, set “DHCP Lease:” to “1 day”

– set “IPv4 DHCP Range:” to something different than your router-modem’s DHCP range , so if your router-modem is at IP-address (like the TG712), set it to something like “ to 200”

– then set “Guest IPv4 DHCP Range:” to yet another range than the router-modem and the primary wireless network – in this example that would be something like “ to 200”

– put a check mark at “Enable NAT Port Mapping Protocol”

– and do not put a check mark at “Enable default host at:”

– then click SAVE

– and click UPDATE

– in the “AirPort Base Station has closed down” warning window, click OK, and wait…

– you might get a question whether you approve that the “Double NAT” error should not be regarded as an error – if so, click OK

– after that, log into your modem-router and set it’s wireless to “Off” and make sure you set a non-standard password for accessing the router-modem !! (*) (else your visitors can still mess with your network pretty easily)

– Done ! enjoy !

Note : if you have an iPhone or iPad, you can use the free AirPort Utility app to switch your Guest Network quickly ON or OFF now… (for instructions look here)


(*) if you have a Speedtouch / Thomson / Technicolor TG712 router-modem (e.g. the one that used to be provided by dutch ISP’s KPN and Wanadoo / Orange / Online / T-Mobile), you should do this as follows :

– in Safari (or any other internet browser) type as the URL

– now your web based control panel for your TG712 router-modem will open

– go to “Home Network” (in the menu on the left) —> “Devices” (in the menu on the left) —> “Configure” (in the upper right corner) and delete the check mark at “Interface enabled:”

– then go to “Toolbox” (in the menu on the left) —> “User administration” (in the menu on the left) and write down the Login (= User name) that is listed there, you will need it later

– the click on “Change My Password” (the link in the middle at the bottom)

– in the page that opens, at “Old password” type nothing (leave blank – there is no preset password), and at “New password” type a password that you’ve never used before and that is hard to crack (if you can’t make up one yourself, you can use OSX’s internal password generator to suggest one to you – look here for instructions) and retype that password at “Confirm new password:”

– then click on the “Cange password”-button and wait for your router-modem to restart

– then login to your router-modem again – this time your will be asked for your login name and password, type both of them and put a check mark at “have OSX Keychain remember these”

– wait for the the web based control panel to open, and then exit by closing the page in your browser

– Done !

Note : don’t be afraid to use a password on your router-modem that you can’t easily remember… if you have it remembered by OSX Keychain you don’t have to… and even if you completely lose the password, you can still reset the modem-router to factory defaults by pressing the RESET button that is on the modem-router housing…

info : could it be my Eye-Fi disturbs Bluetooth ?

Question :

I’ve just installed a Eye-Fi’s WiFi-enabled SD/SDHD-memorycard into my digital camera, and ever since I did so, my Apple Bluetooth mouse is jiggly… it doesn’t fully respond to the movements I make and seems to be disconnected most of the time, even though my Mac isn’t reporting a disconnected mouse… could it be these things have to do with each other ?


Answer :

I’ve not found any info on this on the internet, but I seem to have the exact she problem myself. Since the Eye-Fi card can only use WiFi over 2.4GHz, and there are a lot of other peripherals also using the 2.4GHz band (e.g. Bluetooth-connections), this just might be the case…

The easy solution is exactly what one would expect :

if you make sure that your Eye-Fi-camera stays at least 1.5 meters from your Mac and any Bluetooth-peripherals, you will see that your mouse will start responding normally to your movements…

fixed : get newest version of Flash on PowerPC Mac

Question :

I’m browsing the internet from my G4 (or G5) Mac, and I get a message that I need to update my version of Flash. But when I go to the Adobe Flash download page, I can only download Flash for the new Intel-Macs… what can I do ?

Answer :

The latest versions of Flash for PPC-Macs (like G4 and G5 Macs) are curiously hidden on Adobe’s website… Here’s how you can download & install :

– go to the regular Flash download page :

– then click on the line Different operating system or browser?

– if you would select anything here, you would see that there’s only versions for intel-Macs here, so click on click here (from the line “If your operating system/browser combination is not displayed, click here for older versions of Adobe Flash Player.”)

– If you scroll down that page, you’ll find a table that indicates which version of Flash is the latest one that’s compatible with your G4/G5-Mac’s version of OSX. At the moment I’m writing this, the latest version for “Mac OS X 10.4+ (Power PC processor)” is Flash Player, but for some curious reason you cannot download it straight from the list…

– you have to scroll down further on the page, though an enormous list of versions, to find “(Released 11/04/2010)  Flash Player and (126 MB)”, which is just above the “Android Flash Player versions” chapter.

– then click on Flash Player and to download

– then open the download and unZIP it by double-clicking on it

– then open the folder “fp_10.1.102.64_and_9.0.289.0_archive”, and go to “Flash Player” —> “10_1r102_64” —> “flashplayer10_1r102_64_ub_mac.dmg” and double-click it

– in the window that opens, click on “Install Adobe Flash Player”, and follow the instructions to install… that’s it !

Note : judging from the fact that Adobe is now at Flash Player 11, and the latest version for G4/G5-Macs is Flash Player 10.1, one would assume that support of Flash on G4/G5-Macs is slowly, but steadily, fading…

info : iCloud support for PowerPC Macs ?

Question :

As MobileMe is shutting down by the end of this month, is there any way for me to upgrade my PowerPC Mac to iCloud ?

Answer :

No – I’m sorry. (but you might have some alternatives)

You might be able to keep your … running on a G4 or G5 Mac that runs OSX 10.5 “Leopard” (or even OSX 10.4 “Tiger”) since not much seems to have changed on that front… but that will probably be all that’s left of MobileMe for you…

iCloud’s Calendar and Contacts are dependent on CalDAV and CardDAV syncing, and that wasn’t supported in MacOSX before OSX 10.6 “Snow Leopard” (in OSX 10.5 “Leopard” only CalDAV and CardDV importing is possible, syncing is based on MobileMe and LDAP). So you’re out of luck on those.

And Apple is closing down all iDisks at this moment, so you won’t have that anymore either…

Seems like there are only a few options left for G4 and G5 PowerPC Mac users to keep their info in sync on multiple computers :

1- upgrade to a new Mac (it’s the oct expensive solution, but also the most future-proof, as you will have full iCloud support in OSX 10.7 “Lion”, and you will get a free upgrade to OSX 10.8 “Mountain Lion”) – but that’s the option you might not want to think about, so…

2- start using another way of online calendar and contacts syncing, like Google/Gmail or Plaxo (and something like DropBox as an iDisk alternative) :

Note : if you have an Intel Mac and are still running OSX 10.5 “Leopard” (or even OSX 10.4 “Tiger”), you should upgrade to at least OSX 10.6 “Snow Leopard” (and if your Mac supports it to OSX 10.7 “Lion”) as soon as possible ! OSX 10.7 “Lion” supports iCloud completely, and we are working hard on figuring out how to get iCloud running on OSX 10.6 “Snow Leopard” also… look here for more info :

info : get iCloud on the officially unsupported OSX Snow Leopard

Question :

I have a perfectly running ‘early’ Intel-Mac, that only has a Core Duo processor, not a Core 2 Duo (or newer), so I can’t upgrade to OSX 10.7 “Lion”. I’m ‘happily stuck’ with OSX 10.6 “Snow Leopard”. But… as MobileMe services are permanently stopping within a week, and I don’t have the budget to buy a new Mac I can’t upgrade to iCloud : What can I do ?

Answer :

————- UPDATE ————-

YES ! MacOSX 10.6 Snow Leopard can sync to iCloud

detailed instructions on how to set it up can be found in my other post here :

fixed : get iCloud on the officially unsupported OSX Snow Leopard – sync works !


For people like you, Apple was rumored to implement iCloud compatibility in OSX 10.6.9 about a year ago… but to this date, OSX 10.6.8 is still the newest version of OSX 10.6 “Snow Leopard”…

Based on my good experience with getting iCloud syncing running on the officially unsupported iPhone 3G, one would expect to be able to get a similar solution running on OSX 10.6 “Snow Leopard” also…

…that turns out to be a little more complicated though… OSX 10.6 “Snow Leopard” was the first version of OSX that had CalDAV and CardDAV syncing built in (both needed for iCloud syncing), but the implementation is not as smooth as in OSX 10.7 “Lion”… [ note : OSX 10.5 “Leopard” could only import CalDAV and CardDAV data, there was no syncing ]

But I’ve done som research and I think I’m very, very close to the solution now… [ the only problem is I don’t own a Core Duo Mac myself anymore, so I’m a little crippled regarding testing… ] Some people report being successful using the method outlined below, others – like me – are close, but don’t have things running yet…

Try this method, and please report back on your findings, so we can work out a solution that works for everybody :

–1– find your iCloud Server-number and your 9-digit iCloud Account-code :

How to find your iCloud server and 9-digit iCloud user code :

– on your Mac, go to
– login using your AppleID e-mail address and AppleID password
– click on Calendar
– the online calendar layout now opens
– now go to Window (in the upper menu bar) –> Activity
– in Activity window that opens you’ll find the text “iCloud Calendar” in bold letters, just below it, you’ll find 3 lines that look like this :

– remember that p0X-prefix and the 123456789-code ! you are going to need those in the following steps !

(the p0X-prefix is your iCloud Server-number, and the 123456789-code is your 9-digit iCloud Account-code)

–2– Repair Disk Permissions

– open Programs –> Utilities –> Disk Utility

– select your internal hard drive’s main partition (the one you have MacOSX running on) form the list on the left

– select the ‘First Aid’-tab

– click on “Repair Disk Permissions”

…and wait for it to finish

–3– turn on iCloud Calendar syncing :

– open iCal on your Mac

– go to iCal –> Preferences

– in the window that opens, click on the ‘Accounts’-tab

– click on the ‘+’-button

– in the ‘Add Account’-window that opens, select “Account Type: CalDAV”

– at ‘E-mail address:’ type your AppleID-account’s login eMail address

– at ‘Password:’ type your AppleID password

– at ‘Server address:’ type “”

(in which the p0X-prefix should correspond with the p0X-prefix you’ve found in step 1)

– then click the ‘Create’-button

– the iCloud CalDAV account you’ve just created will now be listed on the left

– in the ‘Account info’-tab, at ‘Description:’ type “iCloud Calendar sync”

– at ‘Calendar synchronization:’ select “Every minute” (or any other option, but do not select “Push”) [ I’m not certain on this one… but it’s my best guess for now… ]

– leave the rest as it is set automatically

– then select the ‘Server settings’-tab, make sure that ‘Use SSL’ is checked

– leave the ‘Port:’ setting empty (it will display “Automatic” in grey) ; if that doesn’t work you might try setting it to “443”

– put a check mark in front of “Use SSL”

– do NOT put a check mark in front of “Use Kerberos” [ I’m not certain on this one… but it’s my best guess for now… ]

– note : the 9-digit number from the Server Path is your 9-digit iCloud Account code ! 

– exit the iCal Preferences by clicking on the little red button in the upper left corner

–4– prepare Address Book and iCloud Contacts for syncing :

– open Address Book on your Mac

– IMPORTANT : now delete any profile pictures from ALL your contacts, as these will create unwanted duplicates when syncing [ that’s right… everything comes with a price… ] and remember to never use new profile pictures until you stop using MacOSX 10.6 ‘Snow Leopard’

– now drag the group (from the list on the left) called “All contacts” (might also be called “On My Mac”) to the desktop of your Mac to create a backup called “All contacts.vcf”

– go online to

– login using your AppleID and password

– then select “Contacts”

– then select all contacts by selecting just one and then pressing the [CMD] + [A] keys on your keyboard at the same time

– then click on the ‘gearing wheel’-icon (a.k.a. ‘sprocket’-icon) in the lower left corner and choose “Delete” from the popup list

– in the ‘Are You sure?’-window that opens, click on “Delete”

– now your iCloud contacts list will be completely empty

– click on the ‘gearing wheel’-icon (a.k.a. ‘sprocket’-icon) in the lower left corner and choose “Import vCard…”

– in the pulldown window that opens, got to your Desktop folder to select the “All contacts.vcf” file you have previously created, and click “Select”

– then wait for all contacts to import…

– when it all imported, select the iCloud button in the upper left corner to return to the main iCloud page and click ‘Log out” in the upper right corner

– then on your Mac, go to Address Book

– select on of your contacts and then press the [CMD] + [A] keys on your keyboard at the same time to select them all

– then press the ‘backspace’-key (a.k.a. ‘backwards delete’) on your keyboard and click on “Delete” to confirm deletion of all your contact

– now your contacts list will be completely empty

REMEMBER : do not add any profile pictures ever again to any of your contacts !

–5– turn on iCloud Contacts syncing :

– then on your Mac, go to Address Book –> Preferences

– in the window that opens, click on the ‘Accounts’-tab

– click on the ‘+’-button

– in the ‘Add Account’-window that opens, select “Account Type: CardDAV”

– at ‘User Name:’ type your AppleID-account’s login eMail address

– at ‘Password:’ type your AppleID-account’s password

– at ‘Server address:’ type “” (with p0X according to your previously found iCloud server prefix)

– click “Create”

– despite the warning that the account settings couldn’t be fetched, click on “Create” again

– then quit Address Book immediately, by pressing the small red button in the upper left corner, and clicking on Address Book –> Quit Address Book from the menu bar

[ Note : quitting Address Book is a very important step in the setup process ! ]

– now in the Finder go to Users –> [your user home folder] –> Library –> Application Support –> Address Book –> Sources –> [folder with an enormous alphanumeric name] –> Configuration.plist

– right-click ( a.k.a. [CTRL]+[mouse click] ) on this Configuration.plist file and select “Open using…” –> “Textedit” from the popup list

– then in Textedit, find the following line :


– change it to this :


(with p0X according to your previously found iCloud server prefix, and 123456789 according to your 9-digit number from the iCal-CalDAV Server Path)

– then two lines below you will find the following line :


(in which “your” is the eMail address that you use as your AppleID iCloud login)

– change it to this :


(with the “@”-sign being replaced by “%40” and “password” being your AppleID iCloud password)

– then select File –> Save and exit Textedit

– now open Configuration.plist again in Textedit to see if the changes were properly saved, and if so, exit Textedit

– then open Address Book and go to Address Book –> Preferences

– select the ‘Accounts’-tab

– select CardDAV from the list on the left

– select the ‘Account info’-tab

– at ‘Description:’ type “iCloud Contacts syncing”

– at ‘User Name:’ type “your” (exactly the way you’ve typed it in the Configuration.plist file previously)

– at ‘Password:’ type ” ” (just a single space)

– then select the ‘Server settings’-tab

– at ‘Server address:’ type “”

(with p0X according to your previously found iCloud server prefix)

– at ‘Server path:’ you won’t be able to change anything, but it should be a “/”, then your 9-digit code, followed by “/carddavhome/addressbook” or “/principal/” or “/carddavhome/” [ I’m not certain on this one… but it’s my best guess for now… ]

– at ‘Port:’ type “443”

– and add a check mark next to “Use SSL” (try “don’t use SSL” also…) [ I’m not certain on this one… but it’s my best guess for now… ]

As mentioned before : this is is said to work for some, but not for all !
Some testing still needs to be done, mainly on these points :
– Calendar Synchronisation : which setting is needed here is not clear, it might be that “Push” will not work
– it is not clear whether “Kerberos” should be used or not in the Calendar settings
– various partial solutions I’ve read do not agree on the path to use for iCloud contacts, but it is probably one of these three :[your 9-digit code]/principal/[your 9-digit code]/carddavhome/[your 9-digit code]/carddavhome/addressbook/
(and in all of them, it might even work better to omit the last slash-sign…)
– one would expect that SSL should be used on both Calendar and Contacts syncing, but that’s not clear either, it might be needed for only one of them, or maybe even for neither…
And there’s one other thing that might be problematic also (maybe because OSX 10.6 “Snow Leopard” was originally only designed to do MobileMe-syncing) :
– things might not work for any iCloud-login name that is not a … address
So… please report back here on your findings !
Thank you !
