Hi,
I have an I Mac late 2009 running off OS X Yosemite 10.10.5 and I need to upgrade to OS X 10.11 or higher but its not letting me? How do I do this? Thanks
Download 10.13 High Sierra here: link-> How to get old versions of macOS - Apple Support
Link-> Download macOS High Sierra 10.13 from the Mac App Store
It states This link needs to be opened with an application SEND TO:?
Open the link with the Safari browser. It should open the Mac App Store page with the High Sierra update.
Other browsers, may not handle it correctly.
Now it states: That it is damaged.
Delete the download and try it again. Its a large download.
How do I delete the download. Sorry for stupid question.
Drag the installer from the Applications folder to the trash, and empty the trash.
Thank you for your help Phil. It worked.
It is interesting that after dragging it to trash, it still appeared on the app and nothing shown in the trash. The direct link provided above also just showed a blank screen
OS Upgrade
