I'm currently using Source Tree 1.4.4.2 on Mac OS X (10.6.8). I've attempted to update to 1.5.3 (Source Tree > Check for Updates > Install Updates), but it fails.
My Mac is configured so that it has multiple accounts, and the account that I usually use is not the root administrator account, even though it has admin rights.
When I attempt to update, Source Tree successfully downloads the compressed update but it cannot extract the file. The failure to extract the update occurs regardless of whether I update Source Tree from root or
my user account with admin rights.
