Macbook IOS High Sierra 10.13.6 update

Is there a way to upgrade an old Macbook 2011 running on IOS High Sierra 10.13.6 in order to have Photoshop and Lightroom working?

Hi @justing28927976 I'm assuming you either have a MacBook 2010 late edition or a MacBook Pro 2011 - either computer can only upgrade to High Sierra. Neither will accept Mojave OS.

The last compatible version of Photoshop was CC2020. If you have that installed, you're ok. If you want to run newer versions, you'll need to purchase new hardware.

If you need a link to download CC2020 (requires a subscription) go here, login and click the chatpod (lower right) and ask for an Agent. Adobe can supply a direct download link for you.

I'm afraid High Sierra is the last version supported on old iMacs. However, you can still use 2019 versions (from ProDesignTools website). It will validate just fine with your new license.

For iMac 2010/2011 users running High Sierra

This worked for me for multiple Adobe software that I needed (and licensed for):

1. Uninstall Creative Cloud App if it is newer than 2020. You might need to uninstall all existing Adobe software to do this.
2. Download 2019 versions of the software from ProDesignTools (If you managed to get any 2020 versions from chat agent, old iMac or other means, you can use them as well)
3. Important: Disconnect from the internet!
4. Install your software, work your way up by year, beginning with 2019, then 2020.
5. Connect to the internet and allow Creative Cloud App to update and retrieve your licensing info.
6. Done
