OSX 10.7 (Lion) Issues

Since I run some software that is not available on Lion, I still have a Snow Leopard partition around. After re-installing Lion because my first installation was broken (could no longer launch 3rd party apps, repairing permissions did not fix that), the AppStore marked all my Apps as "installed", even though they were not installed.

It turned out that the AppStore searched the Snow Leopard partition for installed apps, but installation of new apps still happened on the Lion partition.

The fix was simple: unmount the Snow Leopard partition, then start the AppStore. I alerted Apple to the problem, but I don't think they will fix it.

As mentioned above, I installed Lion two times onto the same partition. Installation happened from a USB stick, and each installation created a new Recovery partition.

My partition table after the second installation looked like this:

mbp:~ beb$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.1 GB   disk0
   1:                  Apple_HFS OSX Lion                229.9 GB   disk0s1
   2:                 Apple_Boot Recovery HD             650.0 MB   disk0s2
   3:                  Apple_HFS Snow Leopard            268.5 GB   disk0s3
   4:                        EFI                         209.7 MB   disk0s4
   5:                 Apple_Boot Recovery HD             650.0 MB   disk0s5

I used the Lion Recovery Disk Assistant to copy the Recovery HD to an USB stick, just in case I deleted the wrong Recovery partition. (It turned out they were identical).

Then I removed the first Recovery partition like this:

mbp:~ beb$ diskutil eraseVolume HFS+ Blank /dev/disk0s2
Started erase on disk0s2 Recovery HD
Unmounting disk
Erasing
Initialized /dev/rdisk0s2 as a 620 MB HFS Plus volume
Mounting disk
Finished erase on disk0s2 Blank

Now the second Recovery was gone, but I could still boot from the remaining one:

mbp:~ beb$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.1 GB   disk0
   1:                  Apple_HFS OSX Lion                229.9 GB   disk0s1
   2:                  Apple_HFS Blank                   650.0 MB   disk0s2
   3:                  Apple_HFS Snow Leopard            268.5 GB   disk0s3
   4:                        EFI                         209.7 MB   disk0s4
   5:                 Apple_Boot Recovery HD             650.0 MB   disk0s5
