Example Project – Objective-C / Swift Mix and Match
No Comments, iPhone & co., Mac, by AndreasPrang.“Actually” () Google Drive is crashing all the time if you try to sync more than ~3000 files. This is because of a memory leak in the app and an other interesting point! Google Drive is an 32 Bit application.
There actually is just one way to sync Google Drive. Restart Google Drive every ~20 Minutes when you got an error message like:
NSMallocException – Attempt to allocate xxxx bytes for NS/CFData filed.
With this script you automatically can restart Google Drive every 20 Minuted for the initial synchronization:
#!/bin/bash while true; do killall Google\ Drive open /Applications/Google\ Drive.app sleep 1200 done DriveRestart.sh

To get the settings enabled for your terminal just download and install the free font and my terminal settings:
- SourceCodePro
- Settings.terminal
- To get the perfect font colors follow my article from 2010: ls –color unter Mac OSX / BSD Unix
Features:

- to get the differences between chars like l and I or O and 0
- not to fat or thin
- monospaced
- …
- Terminal windows in the background are translucent
- Cursor is high visible
- special window title
- background color is a very eye friendly light grey (very close to white)
