Which OSX are you using?

[MattJenko]

Another 10.6.8 user here. I have a very old workhorse of a MacBookPro which would struggle with Mavericks so I dare not tip it over the edge. Stellarium does it enough damage as it is!

For anyone that maybe considering upgrading to OS X Yosemite next month, I have been trialling the beta version on a 2010 MacBook Pro and can report all is working well. Nebulosity, PHD, Equinox Pro and AstroPlanner. I'm also running Parallels 10 with Windows 7 duel installed and that works seamlessly, allowing me to use EQMOD and AstroTortilla.

Astro software aside, Yosemite seems fully functional and no glitches noticed, despite being a beta version. Only issue is iCloud Drive non-compatibility with Mavericks and IOS7, meaning you have to stick with the current iCloud service if any of your apple products are running on a legacy OS, and how long will it be before they stop supporting it? Time to upgrade my iPhone 4 I think, so I can upgrade to IOS8 and transfer everything to the new iCloud service.

Mavericks on MacBook Pro 2011, and a Mac mini 2013 (at the telescope). Running SkySafari 4 Pro, Nebulosity, EQmac, PHD2, Rigel nStep and PhotoShop CS6.

Apparently the SBIG drivers don't work on Yosemite so I won't upgrade until they do. As I'm using TheSkyX pro for everything (AP900GTO mount, SBIG STF-8300M  camera, RoboFocus , FLI filter wheel, Pyxis 2 rotator, plate solving, ...) I'll just wait for Software Bisque to give us the green light for Yosemite. I still use PHD for the guiding as I use IIDC firewire cameras for this (and planetary imaging using Astro IIDC).

The 10.9 update made no difference to the GPU issues with OpenCL.. I think it's a AMD OpenCL optimiser issue.. they're looking into it.. If I make one change in the OpenCL kernel.. and the things works or doesn't work.. that to me sounds fishy..

Hmm.. looks at 10.9 desktop.. looks at ATIK camera plugged in.. looks ok so far:

@NickK, Yosemite = 10.10 

10.9 (Mavericks) works fine for me with TheSkyX Pro and my SBIG camera (not to say that what you did for the Atik is not impressive and more than welcome for OS X users).

Good point..  it's was way past my bedtime! 

[rpineau]

@NickK : me too apparently : "what you did for the Atik is not impressive" should have been "what you did for the Atik is  impressive" ... like yea .. I should read twice before hitting the post button

Keep up the good work, who know I might get an Atik cam one day

Mavericks on my iMac i5/16G  late 2013 and on my Macbook Pro i7/16G Late 2011.  Runs great.  Does not run so great on my Macbook Late 2008 Core2Duo/4G and I may downgrade back to Snow Leopard on that machine.  I don't use any Mac for astro capture  (Win7 PC for that) but do run Pixinsight on the iMac for post processing.

Well I'm one of the 18% still creaking around with Snow Leopard, and proud of it 

I used to be fanatical about upgrading to the latest version of everything going but simply can't be bothered anymore. Maybe it's the start of my slow decline into being a grumpy old man.

There's always one

Actually, the feeling I'm getting is that many of those who can have moved to Mavericks, leaving behind a small number who dare not for compatibility reasons or because they're concerned about their system not being up to it.  And then there are a whole bunch still on Snow Leopard because they're pretty much stuck there anyhow (though I think Lion does support 32-bit if they wanted it?  Not sure about that.)

I am using an iBook G4 (PPC) running Tiger' 10.4...

the problem from a developer point of view is that the support in development tools only goes back a couple of releases with the old hardware and interfaces being actively removed by apple. Hence a 10.9 development tool (Xcode) will not build for 10.6.8 etc. The only way to support old releases like 10.6.8 is either (a) have/maintain old hardware and the development tool.. knowing that any bugs in the tool etc will not be fixed - or - ( use a virtual machine to run the old OSX+xcode which has other problems such as licensing and dodgy hacks to get to work making it just as much of a PITA.

I have an old C2D mini.. with 10.6.8 and 10.9 dual booting as the hardware supports the old version. I assume that with 10.10 I'll loose the ability to upgrade sooner or later. The main dev machine is a MBP i7.. so that's ok for a few releases yet but can't compile for 10.6.8..

[D4N]

Well 10.6.8 is the last OSX to support Rosetta so I run that in a virtual machine on my i7 MBP. It's totally legit to run snow leopard server on a virtual machine so long as it's on a Mac and you own the license. Non server versions require you to trick the vm into thinking it is server version to make it work. Installing old versions of OS X dual boot on new hardware requires you to hack the OS X install files though which is indeed a bit dodgy and you end up with a hackintosh.

Edit: Hmm not sure why it double posted.

Mavericks , a jump from old good Snow Leopard. (Lion and ML were too quirky)

Win7 in Parallels, for various astro stuff that is not present in OSX.

[uhb1966]

10.9 here, with virtualbox + win xp for DSS
