I have retired so now counting pennies. I would like to revert to my original Classic License. I have both Serial Number and Authorization Number but when I open my old plan, I do not have access to insert the foregoing information. Please advise a way forward. ---

What version of SketchUp are you opening? For what version is your old Classic license? ---

The (blue color) SketchUp.app / Layout.app states Wednesday, December 9, 2020 at 09:45. I saved this one prior to procuring the (red) newer SketchUp. (22 Apr 2020). The dates do not match up so confusing. Found the following details; Maintenance & support number: 3192115 Maintenance & support expiration date: 2021/05/16 (YYYY/MM/DD) ---

The dates do not match up so confusing. That doesn’t make any sense. Show a screenshot of what you are seeing. If your maintenance and support expired in mid 2021, you would most likely be entitled to use SketchUp 2021. That version hasn’t been supported for a few years.You can still find the installer file but be aware it may not run on your current system. THere’s a link for the 2021 installer here: > [@Where I can find SketchUp 2021 PRO for download?](https://forums.sketchup.com/t/where-i-can-find-sketchup-2021-pro-for-download/274480/3): > > for some reason it is still on sketchup official website, but not on the english page. here it is on the french one : [https://help.sketchup.com/fr/downloading-older-versions](https://help.sketchup.com/fr/downloading-older-versions) or direct link to download : [https://www.sketchup.com/sketchup/2021/SketchUpPro-exe](https://www.sketchup.com/sketchup/2021/SketchUpPro-exe) (windows) [https://www.sketchup.com/sketchup/2021/SketchUpPro-dmg](https://www.sketchup.com/sketchup/2021/SketchUpPro-dmg) (Mac) ---

I was able to look up your support number, and will send you a direct message to make sure you have the right license details. Look at your avatar in the top right of the page, and you should see when a message comes from me. ---

My bad and apologies. You are totally correct!!! I opened the columns and found that I had the 2021 version then procured the license for 2021. The (Red) 2020 above was incorrect. Everything, changed in 2021. ---

> [@ojosazul](#): > > gave me her old computer that has macOS Sequoia 15.5. OK. Please include that along with the SketchUP version. Note that SketchUp 2021 doesn’t support Sequoia. Others have reported frequent crashes with older versions of SketchUp and newer operating systems. Keep your fingers crossed that you won’t be one of them. ---

The main issue with 2021 and Sonoma and later macOS, is that resizing or changing sections in the Colors palette will crash SketchUp. You will need to manage materials without relying on the Colors palette. ---

Yes, you are correct ojos azules is proper Spanish. I do know the meaning. No issues, when I get back on SketchUp forum, will change the name. ---
