I use a MacBook Air as my primary machine.
When at home in my office, I plug it in to a 27″ Thunderbolt display, and use the Apple keyboard and “magic” mouse – which are connected via bluetooth.
To save battery, when not plugged in, I turn off bluetooth.
When I come back to the office, it’s usually still off, and I have to remember to turn it back on, to use the external keyboard and mouse.
I was looking for a way of automatically turning it on when the OS detects it’s connected to an external display, but couldn’t find anything obvious. Until I stumbled across
Create a context of “Plugged In To Display”
Select ‘Attached USB Device’ in the Evidence Sources tab
In the Rules tab, click add, then “Add ‘Attached USB Device’ Rule… – then select the ‘Plugged In To Display’ context
Finally, in the ‘Actions’ tab, click add System Preferences Actions > Toggle Bluetooth. Set it to ‘On’ and ‘On Arrival’
That should be it!
Now, every time I plug my MacBook into the Thunderbolt display, Bluetooth turns on automatically!
My setup is a fairly standard one:
13″ 2013 MacBook Air, which is occasionally, although more often than not, plugged in to a 27″ Thunderbolt Display.
I “upgraded” to Yosemite last night.
Booted my machine, everything seemed fine. I was downstairs at the time, no Thunderbolt display connected.
This morning, plug in to the TB display, and disaster… Blacked out.
Machine restarts saying it restarted because of a problem. One off I thought….
Then, a few seconds later, same thing.
I unplugged the TB display, and it booted fine.
Plugged the TB display back in, it crashed again. I could replicate and reproduce this every time.
Secondly, if the TB display was left plugged in, then boot the machine, the problem would happen, and it would get stuck in a cycle of booting, crashing, and restarting itself.
I recently upgraded my copy of Parallels desktop from version 7 to version 8.
As soon as I had done, I noticed the supposed “improved multi-monitor support” wasn’t all it was cracked up to be.
If I had a window open, and dragged it to the other monitor (either from external to macbook, or vice versa) it snapped back!
Parallels have now released a hot fix which fixes this issue.
It would have been nice if they’d tested this before releasing in the first place however…
As per their support site, follow these instructions:
Please update Parallels Desktop 8 to the latest build. To obtain the update, please do the following: 1. Start Parallels Desktop > click on Parallels Desktop menu > Check for Updates.. . 2. Download and install the Update.
Just a quick blog to see if anyone else out there is experiencing hanging / crashing when using:
OSX Mountain Lion
SSD (256mb Crucial CT064M4SSD1)
Parallels – Windows 7 Guest OS
Only started noticing the problem since I installed the SSD
Every now and then, the whole system will sort of freeze.
Won’t respond to mouse / keyboard.
Freeze lasts around 10-30 seconds, then returns to normal
Will update this post with any more info if I get it
I recently did a fresh install of OS X Lion on my Macbook Pro
I installed XCode, homebrew, and git.
After trying to install mysql via homebrew:
I received this error:
Error: Failed executing: ./configure –prefix=/usr/local/Cellar/readline/6.2.2 –mandir=/usr/local/Cellar/readline/6.2.2/share/man –infodir=/usr/local/Cellar/readline/6.2.2/share/info –enable-multibyte
If `brew doctor’ does not help diagnose the issue, please report the bug:
So, I did what I was told, and ran:
You have no /usr/bin/cc. This will cause numerous build issues. Please
After some googling (which if you’re reading this, you’ll notice there’s not a lot of results), I found the solution.
Xcode needs the Command line tools installed.
To do this, open Xcode, click the Xcode menu, and select preferences.
Click install next to Command line tools:
