Question

Install Snow Leopard on a 2015 MacBookPro ?

I have a 2011 MacBookPro 13" which runs on 10.6.8 Snow Leopard. It's just over 4 years old and performs as good as new. The only new hardware it got was a new battery about 6 months ago.

Last month I splashed out on a new 2015 15" MBPro i7 16GB SSD the full works.. it runs 10.10.3 Yosemite, and it's absolutely ****. My 4 year old mac with it's i5 processor and only 4GB of RAM runs rings around it, every time, every application. It's faster, it doesn't lag or crash constantly, it's basically just a better computer in absolutely every respect. I've recently decided to rename my 2015 machine the "windows vista" one.

Question is HOW can I get rid of yosemite and install 10.6 Snow Leopard on my new mac? ? Can I wipe the drive completely, or replace it with a new SSD? I understand it'll cost money to fix, but i feel I've no option. As it is, I just bought a €2400 paperweight, as it's about as useful as tits on a bull.

MacBook Pro (Retina, 15-inch, Mid 2015), OS X Yosemite (10.10.3)

Only non-apple apps on it are OpenOffice, Garmin Basecamp and Adobe Photoshop. I might uninstall them and keep the 15" for video editing only and use the 13" for docs, photos and nav. If I had to single out one app that probably cause the most issues I'd say it's "photos". iPhoto was better. Maybe if I uninstall all those Apps and put Lightroom on it might work better ?

You can't install a version of OS X that is older then the one that shipped with the Mac. A 2015 MBP most certainly shipped with a version of OS X that was newer than 10.6.8 so you can't install 10.6.8 on it the MBP.

Please download and install EtreCheck from http://www.etresoft.com/etrecheck

Run it and post the report here.

Anthony,

I would be more inclined to think it's the Adobe product. I have a huge Photo Library and had to purchase 200GB of iCloud storage so it would all fit. I keep originals on my Mac and my Photos app opens up almost instantly. If you can uninstall the third party apps and see if it makes a difference, it might be worth a look.

If you are really keen to run Snow Leopard on you new MBP, do an Internet search and one on these forums for installing Snow Leopard in a virtual machine. It has been done with other OSX's and I suspect it can be done with Yosemite as well. Personally I am not in favor of doing so unless you have compelling needs to do so.

Ciao.

I keep most of my bigger files, raw photos, videos etc. on an external thunderbolt HDD. JPEGs are kept on the internaliy in 'photos'

Just uninstalled Photoshop now and am downloading Lightroom 6. We'll see how this goes. Not uninstalling Basecamp or OpenOffice, need them. Been using OOo for 15 years, fooked if I'm going near pages or numbers, or god forbid, word *shudders a little*

Ok, with Photoshop gone and Lightroom installed, and everything exported from 'Photos' and put into their respective finder folders for LR, it's running better. Impressed with lightroom, which is impressive in itself as I'm not that easily impressed.. will have to give this newer machine time to win me over, maybe if it would buy me a drink or something.

Thanks for all your help, and the speedy replies.. ye guys are the best 😁

In Dublin you might take it to the Brazen Head, had a couple great pints there and Guinness stew 😉

But stories about Dublin can go on and on - we had a terrific three weeks in Ireland in May, and I am happy to report the quality of the pints of Guinness was consistent throughout the country 😝

Somethings not right. My 2015 MBPr is smoking fast. Do you have some kind of 3rd party software installed?

You cannot - a Mac will not run a version of Mac OS X older than the version that shipped from the factory on the Mac. The firmware will not all the machine to boot an older version.

You need to run etrecheck to see which apps are using both cpu and memory to determine who the culprit is. Etrecheck will only take a couple minutes to run.

Ha Ha that's great. I miss Ireland and all the pubs, I have family in Cahir, Co. Tipperary. Will need to plan a trip so my kids can see their roots.
