From beta version 3.59, Shapr3D for macOS will be compatible with **macOS Big Sur** only.

 ![apple_macos-bigsur_moreapps_06222020](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/e/e8313974375032f67cb118404b5ea4046a979f66.jpeg)

If you’re a Catalina user, please [upgrade to Big Sur](https://www.apple.com/macos/how-to-upgrade/) so you can keep enjoying new features and bug fixes. The intuitiveness and power of Big Sur make the latest OS Shapr3D’s powerful sidekick, guaranteeing the best possible designing experience for you.

But before you hit that **Upgrade Now** button, make sure you’ve backed up your Shapr3D designs to iCloud or any other cloud storage service. For more details, hop over to our [Manual](https://support.shapr3d.com/hc/en-us/articles/360016604020-How-do-I-back-up-my-Shapr3D-designs-).

Why jump to only supporting a _brand new_ OS from Apple?! Beta release 3.59.1.849 has totally stopped my ability to work with Shapr3D on my Mac. The suggestion to upgrade isn’t looking at the big picture that sometimes we as the user community can’t just upgrade our Mac’s due to so, so many other reasons. For example, I can’t upgrade to Big Sur due to other non-compatible software plus I did upgrade and Big Sur really isn’t ready for prime time. _Please re-think this move_ in your software development release. Typically, software support at least a couple past major releases from Apple such as supporting back to Mojave 10.14 or High Sierra 10.13. You had Catalina support and I would vote for it to come back please.

Same here.  
Big Sur is still not supported by a lot of audio companies so if you have anything to do with music production you are probably stuck on Catalina for a while.

Please take a look at this list to get a sense of the situation:

I posted in the wrong beta group to say the same thing. Is there a technical reason why Big Sur is required?

Hello @andrew, no worries 🙂 Yes there is a reason, please take a look at this thread:

> [@OS version query](https://discourse.shapr3d.com/t/os-version-query/11142/4):
>
> Yes, the reason is purely technical. Shapr3D for mac is running on [Catalyst](https://developer.apple.com/mac-catalyst/), which is in a poor shape on Catalina, and not available on Mojave unfortunately. If we see significant demand for supporting older macOS versions, we will do it, but that would mean that we have to rewrite the UI from scratch, which does not sound like a reasonable investment, especially considering that most likely the M1 macs will gain very significant market share over the next couple of years. Another issue is that …

Just because I have a late 2013 Imac, which ran fine, and works fine for all of my work with other programs, I have not now invest in a whole new Imac because only 2014 will upgrade to Big Sur, I am not able to upgrade to Big Sur now on my late 2013 model iMac…So I am screwed both ways, cannot no use shape on Imac, and cannot use Big Sur lol, not right…I hate to have to buy a whole new $2000 Machine just to use Shapr

A $599 iPad Air 4 plus $125 Apple Pencil 2 will do the trick.

I already have a iPad 12.9 pro, I never use it lol, but I do all of my designs on a bigger screen, loved the new iMac version of shapr…My desk fits mostly the PC, and not enough room for both…or it’s more unnatural, also the Imac version seemed easier for me to use when I was trying it out.

Big Sur is awful! As a Mac user from the very beginning, I really, really dislike it. The only reason I upgraded was to use Shapr3D, but now I regret it. I would prefer to use Catalina. Big Sur removes everything that makes the MacOS easy-to-use…it’s inelegant, hard on the eyes, and a disappointment for many of us who have spent years using MacOS and really enjoy it.

Really bad call. Big Sur is horrible. I can only agree wholeheartedly with CurlyBee.  
Many people need to use older systems for various reasons.

And there is absolutely no reason for you to drop support. It’s not like the “great new SDK features” would be needed for this tool.

Sad, but that makes me not use Shapr3D. Also a way to lose users… 🤷‍♂️

There are hard technical reasons why we can not support older macOS versions. Since Catalina there have been 3 major macOS updates, Big Sur, Monterey and Ventura. While I understand that OS upgrades can be frustrating sometimes, we won’t be able to keep support for Catalina, particularly because Apple ended support for Catalina in November 2022.
