It’s been 19 months since Apple released the M1 / Silicon developer transition kit. It’s been 14 months since Apple released M1. It’s been about 14 months since the first reports of problems that resembled memory leaks started appearing on your forums.
I have been a paid INSYNC license holder for probably four or five years. I have had Insync up and running for about 2 months total of that. Every now and then I try it, and then I abandon it after a very short trial because it is slow and a resource hog.
Great idea in theory. I think it is not very well executed. I presume you are using a very slow cross-platform framework to make it easier to develop one solution. If that is the case, I think any such choice is a bad choice for apps that run on the filesystem, which is effectively in need of native speed.
