I feel your pain. A (pirated) hackintosh VM doesn't cut it, as I need 3D acceleration to test a very complex WebGL app. And it's the slowest browser from the bunch. Safari is the new IE6 for me. I hate it with passion.
From what I gathered you have 2 solutions for GPU passtrough : if you're a Unix guru and have plenty of time to spare you might make it work with Xen or if you have money VMWare looks easier but you may need a license and special hardware (if you have a regular Nvidia graphic card it won't work, you need an ATI or a Nvidia Quadro).
No. You just need to read Alex Williamson blog, for nvidia you need to patch drivers a bit - it is not hard. And compared to the price of macpro with discrete GPU - not that expensive either.
For anyone else, thinking hmm, that sounds easy. The TL;DR is that you don't "just need to read" Alex's blog, you need to read, think, try, fix, bug search, rinse, repeat, take on board a number of complex ideas and concepts, and/or buy ideal hardware. The arch linux topic is very long! I've read most of it as it came in, but reading that whole thing for tidbits and fixes that Google doesn't always turn up isn't quick or easygoing.
Good luck!
Yeah, I'm definitely a geek and tinkerer, but testing in Safari is work stuff I don't like, and the only way to do it properly is with actual Apple hardware.
Not only that, you need an iPhone and several iPad versions too because they are all different. Supporting Apple devices suck unless that is your main dev platform.
Although in all honestly, it's much less of a problem. Only about 6% uses an iOS version before iOS 8 at the moment. (I'm one of 'm!)
Interestingly, by doing this developers have a harder time supporting me (iOS 6 and 7 on phone/tablet). The result is forgoing app updates and even new apps altogether that I can't download. This pushes me to upgrade, and keeps the iOS adoption rate quite high. Facilitating devs in supporting old iOS versions does the opposite. I'm not a fan of this but I can easily imagine the benefits for Apple.
You're right, it only goes back to iOS 8.1, but you do get the devices for all current iPhone, iPad, Apple TV and watchOS.
Of course having a real device is much better, but as a web developer, this helped me pick up a Safari only bug very easily without needing to spend on a real device.
You can use OSX's debugger in Safari to remote debug a web page in the simulator, which I think is pretty neat.
Is that any worse than Android? I certainly wouldn't think so, given that there are way fewer Apple models and they tend to have way better distribution of their software updates.
Aren't there hosting places where you can rent a mac by the hour or by the month? I just googled "rent a mac" and found a couple. No clue how legit or shady any of the sites are though.
