I have a 1st generation Time Capsule that always used to work fine, but recently it shuts down almost only seconds after I turn it on.
How can I solve this ?
Most of the time, this problem can be solved rather easily.
The cause could be a broken HardDrive inside your Time Capsule (if that’s the case, go here to see instructions on how to replace the HD), but most of the time this specific problem turns out to be an overheated (and therefore broken) power unit.
Even though this type of Time Capsule is marked obsolete by Apple, it will still function in your current WiFi network and can still be configured using the current AirPort Utility app version 6 and newer.
The main problem is probably not going to be to replace the power unit, but finding a new power unit. You might find one on Amazon, but since it will probably be a secondhand item, your will probably have more luck searching for an “A1254 power unit” on eBay, AliExpress or Google Shopping
When you have found a new (secondhand) A1254 power unit, you can build it into your A1254 “1st generation” Time Capsule this way :
put the Time Capsule upside-down and use a hairdryer to heat up the rubber base plate and loosen it’s glue (if you don’t do this, you will probably rupture the base plate when you try to take it off)
then follow the iFixit manual for replacing the power unit and make sure not to skip the important comment at Step 2 : “The two screws in the top center of this picture should not be removed at this time. They are locating pins on the hard drive.”
after taking out the broken power unit and putting in the new (secondhand) power unit in, put your Time Capsule back together doing the iFixit steps in reverse order
after plugging the Time Capsule into the power, you can reinstall it into your WiFi network using the AirPort Utility app on your Mac (or on your iPhone/iPad)
While browsing the internet using Safari, I suddenly got a popup window which I can’t close. I expect it to be a scam, as there is only one button ; an OK-button.
As I don’t agree with the text I am supposed to agree on, and I don’t trust the sender either, I just want to close this popup-window. But the red ‘Close Window’-button is not responding, and I can’t switch to any other open browser windows either. Safari seems to hang.
I could of course restart Safari, but I have several windows open I haven’t saved yet and it would be a real hassle to loose them…
Isn’t there any way to shut this popup down without loosing any other open windows ?
The popup you have encountered is most definitely a scam-popup, as there is no option to ‘not agree’.
It’s rather simple to get out of this awkward situation :
shut down your WiFi-connection : goto the ‘piece-of-pie’ icon in the top menu bar of the Finder –> then select “Turn Wi-Fi Off” from the pulldown menu that appears
pull the ethernet-cable from your Mac
now you’re disconnected from the Internet, you can safely click on the OK-button in the popup-window
the popup-window will now close, and you will now be able to normally use Safari again
now close all other windows you don’t need to have open
even though you could now reconnect to WiFi- or Ethernet-internet, it’s recommended to do the following first
still without internet-connection, open a new browser window : File –> New Window (or just press the CMD + N key-combo)
then open the Reading List sidebar in that fresh window : View –> Show Reading List Sidebar (or just press the SHIFT + CMD + 2 key-combo)
now drag all open browser windows you want to keep to the reading list
when done, clear Safari’s history and website data : Safari –> Clear History…
in the popup window that opens asking you to “Clear history will delete related cookies and other website data.” click on the “Clear History”-button
then close Safari
then reconnect to the Internet (either via WiFi or Ethernet-cable)
and reopen Safari
…you can now find all previously open windows in the Reading List
