So my MBP late 2011 now I want to update it so how will I update it to high sierra I saw videos but all videos are old need help and when they all can find it in the App Store I can’t see it there
The Correct term when moving from Older version of macOS to Newer Version of macOS is upGRADE
The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.
With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install. For Best results use Safari to commence the download as Others may not work.
Safari will open a redirect and open the Apple Store where the download can commence
Make Time Machine Backup is very useful and can be used to Revert to Previous Working macOS
Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation
Tricky wording by OP " how will I update it to high Sierra " seems to imply needing an upGrade to High Sierra ?
Why can’t I find Mac OS high sierra update on the app store
