> Disk and sys­tem main­te­nance tools

Mac|Life - - FEATURE -

Disk util­i­ties, and other apps in­clud­ing some anti-mal­ware check­ers and clean­ing apps, are de­signed to man­age data at a low level and are a po­ten­tial mine­field when you up­grade.

Af­ter you up­grade to High Sierra, don’t even think about try­ing to use your older ver­sion of tools such as DiskWar­rior, Car­bon Copy Cloner, Su­perDu­per, and the like with­out first check­ing the web­site of the pub­lisher to find a ver­sion that’s ex­plic­itly de­signed to work with your new ver­sion of macOS. Don’t say we didn’t warn you.

This ap­plies to any macOS up­date, but par­tic­u­larly to High Sierra due to ex­ten­sive un­der­ly­ing changes. It also ap­plies even if your Mac has a hard drive rather than an SSD that’s been con­verted to the new file sys­tem, APFS. Try­ing to use older ver­sions of main­te­nance util­i­ties such as TechTool Pro, Drive Ge­nius and App Cleaner will not only be un­re­li­able but could cor­rupt your data.

Tech­ni­cal changes that are nor­mally in­vis­i­ble may cause a lot of stress if you use out­dated main­te­nance tools.
