fixed : my Mac can’t unzip this file I’ve downloaded

Question :

Someone just sent me a file over WeTransfer. After downloading it turns out to be a .zip-file, but when I double-click on it to unzip as usual, the Archive Utility does start the unzipping but ends in an error each time, claiming the .zip-file is broken.

I’m pretty sure the .zip-file isn’t broken… what can I do ?

 

Answer :

Even though OSX/macOS’s built-in Archive Utility is your default choice for zipping and unzipping files and folders, it turn out not to be the best choice for unzipping. (Especially .zip-files created on Windows PCs seem to be problematic every now and then…)

The solution is simple : just use an other app to unzip.

There are various payed alternatives like Stuffit Expander and WinZIP, but there’s no need to buy an app for this as most FREE apps ( like The Unarchiver ) will do just fine.

To install & use another app to unzip do this :

  • download a FREE zip/unzip-app from the Mac AppStore
  • after installation, lookup the .zip-file on your Mac ( it will probably still be in your Downloads folder or on your Desktop )
  • right-click on the .zip-file’s icon and select “Open with…” from the pop-up menu
  • then choose your zip/unzip-app from the list
  • …and wait for the file to unzip

That’s it ! enjoy 😉

fixed : What to do with a winmail.dat attachment ?

Question :

I recently received an eMail that should include various attachments, but it only included one : a winmail.dat file.

When I try to open it, OSX tells me there is no app on my Mac that can handle this file.

What can I do ?

Answer :

There are various ways of solving this. (or rather : ‘handling this’, as fixing the actual cause isn’t something an end user can do)

But first, a little insight into the cause :

Long ago, when eMails were still text-only without layout and attachments were added as plain files, a lot of eMail-client makers wanted to improve their user experience and provide their users a layout-option for eMails. Microsoft then developed TNEF as a protocol for communication between their Outlook eMail-clients. But TNEF never made it into an eMail-communication industry standard. HTML (the web-layout protocol) was adopted as the industry-wide standard. MS Outlook never fully adopted regular HTML as it’s eMail-layout protocol. So, even though Outlook calls them HTML-eMail, they are actually being sent as TNEF-eMail, which is HTML-ish, but still MS Outlook-only…

Sometimes (in the chain of eMail-servers involved in eMail-communication) the sender’s Outlook-app (or MS Exchange client) sends out a TNEF-eMail, not a regular HTML-eMail. All receivers of the eMail that use Outlook (or MS Exchange) will not detect any irregularity, but any recipient who’s not using Outlook as their eMail-client will receive it as a text-eMail with only one attachment : a winmail.dat file.

So… this is not a Mac-problem, it isn’t even a problem for all non-Outlook users, it is just that the only way to prevent this from happening to you, is to use MS Outlook…

…but for most non-Outlook users, using Outlook is not an option…

Anyway… the solution …or rather the various options for solving this, as either the sender can prevent this from happening, or the recipient can find ways to open the windmill.dat file anyway :

Microsoft provides 2 options for the sender who wants to prevent this :

1. set Outlook to only send ‘Plain Text’-eMail to any future recipient :

in Outlook, choose “File” (or “Tools”), then “Options”, then “Mail” (or “Mail Format”), and then in “Compose in this message format”, choose “Plain Text”, then click “OK”

2. set Outlook to only send ‘Plain Text’-eMail to this specific recipient :

in Outlook’s Address Book, double-click on the recipient’s eMail-address, then in the “SMTP – Address” field choose delete (un-click) the check-mark at “Always Send To This Recipient iIn Microsoft Exchange Rich-Text Format”, then click “OK”

More info can be found on Microsoft’s website :

http://support.microsoft.com/kb/290809

Even though prevention is the better option, there are alternatives : if you are a recipient using OSX, you can find various apps to unpack winmail.dat files in the Mac App Store. Too bad, there are no free apps for this in the App Store, but there is a FREE one available here :

TNEF’s Enough

If you prefer an automatically updated app from the Mac App Store, and don’t mind paying for it, consider this one, which will unpack faster and has a more comprehensive and visually nicer interface :

Winmail Extractor

If you also need a winmail.dat unpacker-app for your iPhone and/or iPad, you can consider this one :

Klammer for iOS & OSX

There are FREE services available online also, that will convert your windmill.dat for you instantly. Just keep in mind that by using them, you are enabling these services to view the contents of your eMail and it’s attachments, so you are willingly giving up your privacy in suing them. An example :

winmail-dat.com

But, again : even the windmill-dat.com service itself advices you to prefer a dedicated (offline) winmail.dat conversion app (on your Mac) over the use of their service.

fixed : easily collect lots of studs in LEGO Batman 3 “Beyond Gotham” game

Question :

My children are really exited about playing the LEGO Batman 3 “Beyond Gotham” game.

Now they keep asking me how to collect as many studs (money-points) as possible quickly and easily.

Can you help me ?

Answer :

Probably the best place in the entire game to collect stud-money easily is in the “Lantern Menace”-level. There you should electrocute the tentacles on the left side. Then there will be fire. To collect studs, extinguish the fire using a character that has ice-breath (like any version of Superman, Supergirl or Superboy) or an ice-gun (like Captain Cold, Mr. Freeze, Geoff Johns and Batman in Arctic Suit). Note that this can be done extra quickly when playing the game with two players instead of just one, since simply switching players enables you to continuously collect studs, either through player 1 or player 2.

Using the Red Bricks for “Studs x2”, “Studs x4”, “Studs x6”, “Studs x8” and/or “Studs x10” will of course multiply your collection of stud-money even more…

That’s it.

Enjoy !

fixed : run DOS commands on your Mac

Question :

I need to run a firmware update for a hard drive, but there’s no firmware update available for MacOSX, there’s only a firmware .exe-program for MS DOS.

How can I run that on my Mac, since I don’t have a Windows-PC available ?

 

Answer :

MacOSX isn’t able to run DOS commands in the MacOSX Terminal.app…

and running FreeDOS from a USB-stick isn’t an option on your Mac, since your Mac can’t boot from non-EFI volumes…

but there’s a very simple option to run DOS commands in OSX :

– download & install Boxer by drag&dropping the app into your Applications folder

– run the Boxer.app and you will get 3 options, one being “Open a DOS prompt”, that’s the one your looking for

– click on it, and you will have your DOS-prompt

– and just as you can in OSX Terminal.app, you can drag&drop .exe-files (and other files) into the prompt, and the correct path to the file will be automatically inserted into the prompt

– there’s just one small drawback : the Mac’s keyboard layout is not supported… so even though the letters will be what you see on your keyboard, most other characters will not… to get a – [minus], you should type / [slash], and to get ” [brace], you should type @ [at] on your Mac keyboard… (you can figure out the other ones yourself by just trying)

That’s it !

Enjoy !

tip : get the latest versions of Word, PowerPoint and Excel for FREE, legally

If you are looking for a FREE (and legal) version of the latest version of MS Office, you just might be in luck :

Microsoft is offering the newest version of MS Office for FREE to students and staff of schools and universities that have licensed MS Office.

This program has run in the US since 2013 under the moniker “Student Advantage”, and is now available in the Netherlands also.

What you get is a FREE one year license to Microsoft’s online cloud service “Office 365”, in the “Pro Plus”-version, including FREE downloads of the latest versions of Office to be installed on maximum 5 Macs or PCs and on maximum 5 Android or iOS devices (like iPhones and iPads).

These latest versions are Office 2011 for Mac and Office 2013 for Windows, both including Word, PowerPoint, Excel, Outlook, OneNote, Skype and OneDrive (Microsoft’s cloud-drive formerly known as SkyDrive).

In the Netherlands, these FREE versions are available for two specific groups :

1- (parents of) students of the primary schools [“basisschoolleerlingen” in Dutch] https://www.surfspot.nl/officeleerling

2- students of (some) higher education [“Hogescholen en Universiteiten” in Dutch] https://www.surfspot.nl/officestudent

The procedure to get this (nearly) FREE software, is quite complex, but it’s well worth the hassle :

– first you need an account at Surfspot.nl (the website for educational discounts)

– then, you need to ‘buy’ the FREE version of Office 365 Pro Plus

– with that, you’ll get a voucher (which might take several days due to popular demand)

– using that voucher, you can activate Office 365 at Microsoft, and you will get FREE download-links to the latest versions of Word, PowerPoint, Excel, Outlook, OneNote, Skype, OneDrive, etc.

–  those apps you can install on maximum 5 Macs or PCs and 5 iOS or Android devices

 

…as mentioned : it’s a hassle, but it’s well worth it !

Enjoy !
