Upgrade issues to macOS High Sierra
We are seeing a few failed High-Sierra update issues coming through the workshop recently.
Here are the common causes:
- Corrupt installation file (wi-fi, power or internet dropped out whilst downloading or installing.
- Make sure power cord is in and preferably connect to internet via an ethernet cord
- Corrupt installtion due to shortage of available diskspace
- High Sierra is a big download, Please amke sure you have plenty of available disk space before attempting the upgrade
- Failed HDD or SSD
- These tend to fail at the most inconvenient times, usually while doing an upgrade
- Computer is too old
- if your Mac is older than 2009, it’s not going to work (see full list below)
- Not enough memory (RAM)
- Your mac will need a minimum of 4GB RAM to upgrade to High Sierra.
- Encrypted Hard Disk
- To upgrade to High Sierra, your drive needs to be decrypted
No matter what the issues is, The IT Guys can fix it, please bring your Mac to our workshop in Subiaco, No appointment necessary.
If the installation fails, your computer goes to sleep or there is a loss of internet connection, you may corrupt the operating system and may then need to restore from the last full backup.
The upgrade is also only available for the following Mac models
