AspeQt for OS X El Capitan

I updated and compiled AspeQt with QT 5.5.1 and made a build for OS X El Capitan. This has been requested for a while, but i never came around to install latest QT and get it working again. So here we go….

AspeQt for OSX

2 years ago i started to transfer my old Atari 800 XL software from the 28 years old “5,25 disk to ATR images on my laptop. But i was never happy with the setup using a windows program in a vm to do the transfer. I found AspeQt which is opensource, but it did not support OSX. So i started to add an serial driver with OSX support to it. And then forget about it. Till recently when i got an email from the AspeQt maintainer Ray who asked about the state of my github repo. Since i want OSX support in the mainline, i picked the lastest version of AspeQt to update my repo, which already got a little stale. Then i found out that is a pain in the ass to run QT4.8 on Maverick, there is no offical package and building from source you end up in patch hell.

So i decided to move my branch of AspeQt to QT5.2, which was pretty straight forward.

QtCreator is not a great editor but does the job
