Re: safe to upgrade my Mac?

8.10.3 works on every more recent OS X. That said, I’m waiting for cabal 3.4 Release, which 8.10 can build, before I do the Big Sur update. On Thu, Jan 28, 2021 at 2:35 AM Alfredo Di Napoli < alfredo.dinapoli@gmail.com> wrote:

Hi Richard,

I am running 10.15.7 and I think I upgraded to Catalina months ago (but I don't exactly recall when). From my experience, everything works just fine, at least for my current workflow (clients' projects, GHC development etc). At work I have successfully used GHC 8.6.5 and 8.10.2 for various projects, both with Cabal and Stack and didn't experience any major problems.

In terms of performance, I cannot judge. If it got slower, I certainly didn't notice.

I hope it helps! :)

I just (finally) upgraded to Catalina last week and the 8.10.2 bindist works just fine (you have to fiddle with xattr after unzipping, there's an issue on gitlab that has the right command in there). If you're going to Mojave then there's 0 issues. Big Sur I haven't tried yet.

If I upgrade, will GHC hate me? That is, will GHC 8.10 continue to work? Will I continue to be able to compile GHC? Will it be as performant? (A few years ago, I had a strange issue on a secondary computer where any binary built by GHC was horribly slow; we never got to the bottom of it.)

I didn't notice any performance regressions, but I also haven't paid close attention.
