is photoshop cs4 compatible with windows 10

also your video card drivers may need updating to run opengl on CS4.

Right click on the CS4 icon, choose properties, click on compatibility tab and put a check mark in run as admin. I think Brent Simmons, creator of wonderful Cocoa apps like NetNewsWire, put it most elegantly: 'Finder + Cocoa = Finder.' That is, rewriting one's app in Cocoa doesn't somehow automatically improve its speed, usability, or feature set. When you get CS4 installed, the very first time you run the software you have to run it as admin. Most Mac users don't know Cocoa from Ovaltine, and nor should they: it's just an implementation detail, not a measure of quality. He also tries to dispel the notion that Cocoa alone will produce a higher quality product than Carbon: Nack reports that they started working on the transition immediately after the announcement but due to the scope of the transition are unable to deliver it by CS4. This means that we'll need to rewrite large parts of Photoshop and its plug-ins (potentially affecting over a million lines of code) to move it from Carbon to Cocoa. This means that 64-bit Mac apps need to be written to use Cocoa (as Lightroom is) instead of Carbon. The reason for this delay is due to Apple's abrupt dropping of Carbon 64-bit support:Īt the WWDC show last June, however, Adobe & other developers learned that Apple had decided to stop their Carbon 64 efforts. With these massive sizes and with enough RAM (32GB given as example), you can see substantial (10x) improvements.Īdobe expects that Mac users will have to wait until CS5 before getting full 64-bit support. This program also supports repairing corrupt PSD file on Mac computers with OS Leopard, OS X Snow Leopard, Lion, Mountain Lion, Mavericks and Yosemite. The reason for the discrepancy, however, is not due to a lack of interest or support from Adobe, but for more practical reasons.įirst off, Nack admits that the 64-bit version of Photoshop will see modest speed increases (8-12%) but the biggest advantage will be for those using massive images (a 3.375 gigapixel image is given as an example). It is compatible with Windows 10, Windows 8, Windows 8.1, Windows Vista, Windows XP, Windows 7, Windows Server 2003 and Windows Server 2008 operating systems. I recently upgraded to a Quad core 3. The Mac version of CS4 will remain at 32-Bit. Adobe Photoshop CS4 for Windows comes as both a traditional 32-bit application and a 64-bit version for systems with the processor and operating system to run 64-bits.

Adobe's John Nack writes about the future plans for Adobe Photoshop CS4 and CS5, revealing that Adobe Photoshop CS4 will include 64-Bit support, but for Windows only.
