Disable BTT accessibility popup
Just updated BetterTouchTool to V2.645, finding that the accessibility permission popup cannot be dismissed. The close icon at the right corner of the popup panel is just missing. Luckily, BTT can work well for touch/click functions without those accessibility permissions. After some searching around, one github issue comment has the way to diable the popup:…

Fix to delete time machine backups for no-responding finder
My MacBookPro was forced to upgrade to High Sierra, because XCode 9.3 is only available on 10.13 to support development for iOS 11.3. The new operating system looks quite the same, except the ridiculous wordings of the Chinese translation of system UI. As usual, I made a Time Machine backup before the upgrade. Since my…

WinToGo 8.1 on rMBP mid 2012
This blog has detail instructions to install USB WinToGo for Mac. But things won’t go that smooth on pre-2013 rMBP.

Just encountered a mysterious problem after upgraded to 10.11.4 that every time MBP reboots and logins, my trackpad settings like tap-to-click are lost.

Annoying iCloud Photo Library Upload Stuck Problem
My iPhone6+ got stuck when uploading some photos automatically to iCloud Photo Library. It’s quite possible if the phone’s available free space is lower than 400MB when using optimizing size option, which might be required by the mysterious blackbox photo upload process. But after cleaning up disk space, it still paused at the “uploading xx photos”…
