The last time I installed a new disk image on an SD Card for the Pi I had to use the Win32DiskImager util on Windows. Since I primarily use a Mac that took a few additional steps to get a working SD Card.
In general, most things on the Mac are pretty intuitive and easy to find/use/work out. Now and then though I come across some feature that seems to have been buried and only find it via someone else talking about it online. for example, how to browse Time Machine backups on an external drive from an older Mac.
I have an external drive that I use for my Time Machine backups, and used it from my older MacBook Pro, and also use it for my newer MBP. The drive filled up, so I was trying to work out a) how to browse my older backups, because by default they weren’t browsable via the Time Machine UI, and b) how to delete some of them.
Turns out, thanks to these tips, if you hold Option while the Time Machine dropdown menu is displayed from your toolbar, the option ‘Browse other backup disks…’ appears – from there you can select the Time Machine backup from another Mac.
While in the Time Machine UI, to delete a whole backup from a prior date, click the ‘cog’ icon and you have the option to delete backup.
Part of the instructions for setting up Virtual Box to boot from your Bootcamp drive on Mac OS X walk you through setting up a permanent approach to unmounting your Bootcamp drive. I didn’t follow those instructions, instead created a script that I can use to run manually to unmount and open the permissions when needed, i.e. when I want to boot from VirtualBox:
diskutil umount /Volumes/BOOTCAMP sudo chmod 777 /dev/disk0s4
The instructions on some sites also assume that your Bootcamp drive is partition disk0s3, but on my machine it’s disk0s4. If you run ‘diskutil list’ you can get a list of your partitions to work out which is your Bootcamp partition.
I have XP in my Bootcamp partition which I occasionally boot to run apps that I don’t have on Mac OS X, usually it’s for a Windows game. It annoys me to switch between Mac OS X and booting Windows from Bootcamp, as it takes a while to switch back and forth. The only reason I’ve ever considered buying Fusion or Parallels is to be able to boot from the Bootcamp partition and avoid having two Windows installs – one in Bootcamp and one on a virtual disk. Sometimes it’s fine to boot in a virtual machine, but othertimes you really want to boot natively to make full use of the graphics card and DirectX etc. Turns out you can set up VirtualBox to easily boot from a Bootcamp partition, and avoid having two installs.
I followed the instructions here, and after a bit of fiddling with with VirtualBox settings for my new VM, it booted fine. The instructions are for booting Windows 7 from Bootcamp in VirtualBox, but it works the same for XP too.
