How to Fix Box Sync's Finder Crashes and Missing Sync Icons

This is for OS X 10.6.8 and BoxSync 3.3.51.

Box Sync (from Box.com) seems to have a bug caused by a Safe Boot of the Mac where after a normal boot -after a Safe Boot- BoxSync will cause the Finder to crash and relaunch after BoxSync, well, syncs.

Also, all the overlay icons like the checkmarks and orange syncing icons will be gone.

It's a bug in BoxSync and here's how to fix it.

0. Quit BoxSync from the Menubar by clicking on the "b" and selecting Quit at the bottom.

Now quit all the apps that are running. Yes, all of them.

1. Download Onyx from here. (be super-sure you get the right version for your version of Mac OS X)
2. Launch it.
3. Let it run it's initial SMART and Verification checks which may take enough time to make some coffee and get a snack. You can just hit Cancel twice if you want to but it's a good idea to let it run these checks.
4. Enter your Admin password.
5. Click on "Automation"
6. Un-tick everything except "LaunchServices" and "dyld's shared cache" under Rebuilding.
7. Hit "Execute" (if you didn't quit all apps before step 1 you'll have to to continue now anyway)
8. Let Onyx do it's thing.

Reboot. Seriously.

After the Mac is booted you should have seen the Finder NOT CRASH when Box Sync launched and synced. If you missed it, that's okay.

9. Now, go to System Preferences (from the Apple Menu is the easiest way generally) and then click on "Box Sync" then click on "Sync Now".

The Finder shouldn't quit and relaunch. That's good!

But your overlay sync icons in Box Documents in the Finder may still be missing. That's bad.

10. So, in System Preferences in Box Sync click on "Settings..."

11. Then hit "Force Uploads". And see if your overlay sync icons return. If no, hit "Force Downloads" and see. One of them should cause them to return.

Done.
