Photoshop CS1: Why is running PPC version of PS slow on an Intel MacBook Pro (mid 2010)?

I was using Photoshop CS on a PowerMac G5 Dual 2.0 (PCI-X) with 8GB RAM and it was fast. Recently I changed to a 2.4 GHz MacBook Pro (mid 2010) Core 2 Duo with 4GB RAM and Photoshop CS seems much slower. The projects I'm doing are about 100MB and consist of about 60 layers.

I understand that CS is a PPC program and the MacBook Pro is Intel, and I'm guessing that the problem lies in that and the Rosetta translation program. I read somewhere that Photoshop CS2 was also slow but that Photoshop CS3 would run fast on Intel Macs. On Wikipedia it says that CS3 had native support for the Intel Macs. Is that the problem I'm having... feel like I went from a V8 to a 6 or even 4 cyl...

Is that accurate info, would CS3 run fast compared to CS on my Intel MacBook Pro? Is that what I'm looking for and is it cheaper for me to get an upgrade since I have PS 5 and CS registered to me?

Hi Ian,

Yes, running a PPC app using emulation is going to be super slow.

We no longer sell CS3. What version of OS X are you running on your Macbook?

The cheapest way to get a version of Photoshop run on modern OSes and hardware is here: https://creative.adobe.com/plans/phot...

Thanks, I'm running 10.6.8.

For some reason I reject any version running off of the internet, the internet here is flaky so I'd want a version on my computer plus I'm not in the position to be buying a $500+ program.

I don't use much as far as filters and effects, the only one is blur, my art is very analog old school actual drawing on paper stuff :)

CC isn't 'run of the internet' - it installs locally and runs on your computer the same as CS.

Oh, the "creative cloud" and monthly/yearly fees threw me off.

What does "per month" and "per year" mean? That sounds like a lease. I wouldn't want that, I want a program that I can buy with one payment and then own.

I'll download it and try it, thanks.

That didn't work. since I'm using Snow Leopard I got the "You are running an operating system that Photoshop no longer supports. Refer to the system requirements for a full list of supported platforms".

No surprise there.

Does your laptop allow you to run anything newer than 10.6? Apple no longer supports that OS.

One thought is to get a copy of Elements 11 (old version) off of Amazon: http://www.amazon.com/Adobe-Photoshop...

If you need more power than that, CS6 (old version) is about the only thing that runs on 10.6.

You are welcome to purchase Photoshop CS6 using the old pricing model at $699/$999 from here:

http://www.adobe.com/products/catalog...

But consider this: at that price a you can have the Creative Cloud Photography Plan @ $9.99/mo for close to 6/8.5 years:

https://creative.adobe.com/plans/offe...

The Creative Cloud Photography Plan includes Photoshop CC, Lightroom, Lightroom mobile, and get all the product updates/upgrades (e.g. Photoshop 2014, 2015, 2016, etc & Lightroom 6, LR7, LR8, LR9, etc) for OS compatibility and support during that time. With the old model, you'd have to pay extra for upgrades in that same time period.

One of the reasons for moving to this model is to make sure customers can keep up with the fast changing technology landscape where Apple and Microsoft are updating OSes every 12 months and introducing new hardware and devices at a faster and faster rate.

Mac OS X 10.9 and 10.10 are free upgrades if you laptop can support them.

Hope that helps

Photoshop CS does run on OS 10.6, but somewhat slow and I had read that CS3 runs "up to speed".

Cost wise, the best thing is to buy a $120 G5 and run CS, which worked fine.

There really has been nothing added in the last 15-20 years on Photoshop or Mac OS upgrades that I've wanted.

That's because CS3 is Intel native code for x86 processors, and doesn't suffer the penalty of emulation that old PowerPC code does.
Plus more recent MacOS versions no longer support Rosetta (the PowerPC emulator).

Sounds like you're missing out on a LOT of features added over the years.

Yes, Chris, the Wikipedia version history said that CS3 is Intel. That's what I was wondering, if CS3 would be what I need to fix the slowness I didn't have on a PPC G5 and do have on my Intel Macbook Pro. I'm concluding that the answer is yes.

I wan't sure about Jeffrey Tranberry's comment that "CS6 (old version) is about the only thing that runs on 10.6" since isn't 10.6 what was current when CS3 came out?

Yes, for most Photoshop users they'd say I'm nuts for missing out on the added features but art is not that way, you just need what you need to get the art inside of you out. I see a pencil and a piece of blank paper as actually being more sophisticated than any computer. I can do more with it, it's more directly connected to my mind, there's more potential.

You don't specifically need CS3 - you need a version of Photoshop that is Intel native on MacOS, and CS3 was the first Intel native version for Macintosh.

If you are running MacOS 10.6.8, then Photoshop CS6 is the latest version which still supports 10.6.8.

Good, thanks, so CS3 through CS6 are what I'm looking for.
