5 or so days ago, this error suddenly popped up:

Unable to complete backup. An error occurred while creating the backup folder.

I have a Raspberry Pi, acting as TimeMachine (using afp/Bonjour/Netatalk).

There are several things I tried to solve this, including messing in the sparebundle from Linux (chowning) and deleting my TM .plist. This probably messed up my backup a bit.

But what seemed to ‘solve’ it for me was:

This.

Used my Raspberry Pi, with an USB disk as TimeMachine. Another disk as NAS/storage. It’s just quite slow… Not sure whether it’s my WiFi or RPi that can’t keep up.

But for now, it’s working.

For no clear reason, OpenVPN on Mac with Tunnelblick (any version, had this problem for a few years already) results in these kind of error messages (and refuses to connect):

2013-02-05 17:44:31 write UDPv4: Can't assign requested address (code=49)
2013-02-05 17:44:33 write UDPv4: Can't assign requested address (code=49)

This seems to appear more often when swapping WiFi/IP range (after my Mac goes into sleep). But also happens when connecting to the same WiFi. It doesn’t change anything whether I disconnect OpenVPN before putting the Mac to sleep.

Okay. This one took a long time to solve.

At some random point after upgrading from Snow Leopard to Mountain Lion was unable to add new printers.

As I don’t really add new printers on a daily base, I have no idea when it actually happened or what might have caused it.

• If I deleted an existing printer, and tried to readd it, it would throw errors at me.
• Plugging in (known) printers would pop up the dialog "click here to install/download/search for the printer driver", even though it was installed. Clicking install would give me an error no drivers could be found.
• Dymo Labelwriter shizzle stopped working.
• The driver list (system pref > printers > add > select printer software) would be empty, while on another Mac it was fully populated.
• Mac would never find the printer driver for the printer, requiring manual intervention (but, yea, as the list was empty, there wasn't much to select).

This is, as you might guess, quite annoying. Unable to print any new labels or print out any papers (and invoices ! -.-) ) I had to use another Mac just for printing.

I reinstalled my Mountain Lion, and since then Adium keeps asking for passwords on every Adium restart/startup. Understandably, this is quite annoying.

I’ve tried the following:

• readd the accounts
• reinstall adium
• run keychain first aid
• check this
• reboot
• pray to the gods, old and new
• check console (which is spawning a thousand million errors about read access denied, but Google told me it's a known Mountain Lion bug)
• update to Mountain Lion 10.8.2

What I did to solve it (I believe):

• Uninstall Adium completely (tada)
• install 10.8.2 (well, I happen to reboot just after uninstalling and reinstall Adium, so I'm unsure whether the first or 2nd point was most useful).

And it's now working correctly. So far.

Downside: have to readd all accounts (Google 2-step verification fun, and time to delete those old accounts (xmpp/icq) where I forgot the passwords), and reset all your settings.

I recently dared to upgrade from Snow Leopard (10.6) to Mountain Lion (10.8), skipping Lion (10.7) altogether.

One of the mayor disturbances I had, was when I was using my Macbook Pro at my home office. I use an external display (some Samsung SyncMaster) as well as my MBP’s main display.

I put my MBP to sleep by simply closing the lid, keeping the power source and external display attached.
