A photo editing machine has a different job than the one I cut video on, and it took me a while to respect that. Lightroom Classic and Photoshop spend most of a session on one or two cores: a brush stroke, a slider, a page of thumbnails. Memory decides whether a 45-megapixel RAW opens without the drive stepping in, and the GPU only wakes up for a short list of jobs, Denoise and the AI masks chief among them.
That’s why the most expensive Mac is rarely the best photo Mac. A $1,299 Mac mini handles a working catalogue from a 45-megapixel body. The $2,299 Mac Studio makes sense when the files are 100 megapixels, the panoramas run to a dozen frames, or Denoise chews through hundreds of images a night. A lot of photographers are getting sold the Studio for work the mini does.
I run Macs every day for post and VFX work, so what follows is my read of how the same silicon behaves when the job is Lightroom and Photoshop instead of Resolve, with Puget Systems’ hardware guidance and Adobe’s own requirements as the reference. There’s a Mac at each budget, one Windows tower, and a ruling on where the catalogue lives when the internal SSD is small.

This is the photo half of a pair. My Mac-for-video guide, best Mac for video editing, covers the same machines from the colorist’s side of the desk, where GPU cores, memory bandwidth and the ProRes engines decide the pick. The two slates don’t match, and the reasons why are over there.
TLDR
If you just want the answer: the Mac mini M6 with 24GB and 512GB at $1,299 is the photo editing computer I’d point most people at, Mac or Windows. The value pick is the same machine with 16GB and 256GB, the Mac mini M6 at $779 on Amazon ($899 list), plus an external SSD for the originals. The Mac Studio M5 Max is for 100-megapixel files, panoramas and tethered studio days. On Windows, the Dell Tower with 32GB and an RTX 5060 is the prebuilt that gets the memory tier right, at $1,699.99.
The picks
Best overall: Mac mini M6 (24GB, 512GB)
24GB of unified memory is why this config sits at the top, and it’s the same reason I tell video editors to skip the $899 base. Puget’s Photoshop guidance puts 16GB as enough for documents under 500MB with layers counted; 24GB clears that with room for Lightroom Classic and Photoshop open at the same time, which is the case Puget flags as needing more. The Mac mini M6 with 24GB and 512GB is $1,299 at Amazon, and the 512GB SSD holds a big catalogue with its previews while the originals live on an external drive.
The chip is a 12-core CPU with a 12-core GPU, and the GPU carries Neural Accelerators that handle Denoise and the AI masks. Most of a Lightroom session is lightly threaded, so the M6’s per-core speed does more for a photographer than the core count on a Pro or Max chip does. Memory tops out at 32GB and can’t be changed after purchase, and the ports are Thunderbolt 4, so a single external SSD runs slower here than it would off the Pro or the Studio. The 16GB model below saves $400 and keeps the same chip.
Best budget: Mac mini M6 (16GB, 256GB)
$779 on Amazon buys the same M6 chip with 16GB and 256GB, $120 under Apple’s $899 list. 16GB is Adobe’s recommended memory figure for Lightroom Classic and the shared-memory figure it names for the AI features on a Mac, so the Mac mini M6 at $779 sits right at the requirement with no headroom. For a 24 to 33 megapixel body and one app open at a time, it’s the cheapest desktop I’d put on a photographer’s desk.
The 256GB SSD is the constraint. macOS, both Adobe apps and a catalogue with previews fit; the originals don’t, so this config needs an external SSD from day one, and a Samsung T9 2TB covers it. AI masks across a few hundred frames will push 16GB into swap, which slows the batch down but finishes it. If you can stretch the extra $400 to the 24GB model, the memory is the part you’ll feel.
Best step-up: Mac mini M5 Pro (24GB, 512GB)
307GB/s of memory bandwidth, double the M6’s 153GB/s, is what the extra $300 buys you. The Mac mini M5 Pro with 24GB and 512GB is $1,599 at Amazon, with a 15-core CPU, a 16-core GPU, Thunderbolt 5 and memory configurable to 64GB. There’s no M6 Pro Mac mini, so this is the Pro tier of the mini for the 2026 cycle. It’s also the mini I recommend most often to video editors, and only part of that reasoning carries over to photo.
Where you’ll see the difference is Denoise batches and exports, the two Lightroom jobs that use the GPU and every core available, and in a 48GB or 64GB config that holds a 100-megapixel catalogue without stepping up to the Studio. The base 24GB model is a hard sell against the $1,299 M6; the config that justifies the Pro is 48GB from Apple’s configurator.
Best for 100MP RAW, panoramas and tethered studio work: Mac Studio M5 Max (36GB, 512GB)
This is the Mac I’d buy for a grading suite without a second thought. For photo work it’s a narrower call, and 36GB of base memory, configurable to 128GB, is what moves a medium-format shooter to the Mac Studio M5 Max, $2,299 at Amazon. Puget puts a 500MB to 1GB Photoshop document at 32GB and anything bigger at 64GB or more; a layered 100-megapixel file or a ten-frame panorama merge lands there. The chip is an 18-core CPU with a 32-core GPU, and the ports suit a studio desk: four Thunderbolt 5, a front UHS-II SD slot and 10 gigabit Ethernet.
For a 45-megapixel catalogue this is $1,000 over the M6 mini for speed that shows up only in Denoise and export. The Mac Studio M5 Ultra at $5,499 list is a step too far: Lightroom’s lightly threaded work gains nothing from the extra cores. The M5 Pro mini at 48GB is the cheaper route to the same memory tier.
Best all-in-one: iMac 24-inch (M6, 16GB, 256GB)
The 24-inch 4.5K P3 display is the pick here, with a computer attached to the back of it. Apple announced the M6 iMac on October 27, 2026: $1,499 for a 10-core CPU and GPU, $1,699 for the 12-core chip with four Thunderbolt 4 ports, 2.5Gb Ethernet, Touch ID on the keyboard and the nano-texture glass option, both with 16GB and 256GB, both shipping November 6. The 12-core at $1,699 is the one to order: the ports and the wired network matter on a desk with a catalogue drive and a backup, and nano-texture is the only matte glass Apple sells at this size. A P3 panel at that resolution bought on its own costs most of what the whole machine does. If you want one cable to the wall and zero monitor research, it’s the only Mac here that arrives finished.
The chip is the same M6 as the Mac mini above, a 12-core CPU with a 12-core GPU whose Neural Accelerators handle Denoise and the AI masks, with the same 32GB ceiling. It runs both Adobe apps on 16GB, and the 256GB SSD puts the originals on an external drive. Against the M6 mini with the same 16GB and 256GB at $779, the display, the camera and the speakers cost about $920. The outgoing iMac M4 with 16GB and 256GB was $1,614 on Amazon on October 26, and it’s the sell-through buy for a Lightroom desk once it sits a few hundred dollars under the new model: same panel, same two Thunderbolt ports as the base M6, an older chip that does the job. If the display is negotiable, the M6 mini and a separate monitor get you the same chip and a screen that outlives the computer.
Best Windows desktop: Dell Tower (Core Ultra 7 265F, RTX 5060, 32GB)
32GB of DDR5 is why this tower gets the slot over a gaming case. Puget’s Lightroom Classic workstations start at 32GB, the memory tier most sub-$2,000 prebuilts skip in favor of a bigger GPU. The Dell Tower is $1,699.99 at Best Buy with a 20-core Core Ultra 7 265F, an RTX 5060 with 8GB and a 1TB SSD. The processor is the right one: Puget’s March 2026 Lightroom Classic 15.2 analysis put the Core Ultra 7 265K at the top of its CPU chart, and the 265F is the locked version of that chip without integrated graphics.
The GPU is the compromise. The RTX 5060’s 8GB sits right at Adobe’s dedicated-memory floor for the AI features, and Puget measured the 5060 noticeably slower than the 5070 class on export and Denoise; it’s the part you’ll swap in two years. The gaming-case alternative is the HP OMEN 35L at $1,959.99 at Best Buy, the tower from my PC build guide: an RTX 5070 with 12GB that finishes Denoise faster, paired with 16GB of memory and a last-generation Core i7-14700F. For photo work it needs a 32GB kit on top of the sticker, which puts it $300 to $400 over the Dell for a better GPU and an older CPU. The Lenovo Legion Tower 5i at $2,399 is $700 more than the Dell for the same memory; skip it.
One more shape: a MacBook Air closed on a stand is a photo desktop for anyone who also edits on the road. The MacBook Air 13-inch M5 with 16GB and 512GB is $1,149 at Amazon and the 15-inch M5 is $1,499 at Best Buy; both are fanless 10-core machines that slow down on a long Denoise batch where a mini wouldn’t, and both are complete for culling and developing. The MacBook Pro tiers, which add a fan and more memory, are in our best laptop for video editing guide.

What matters
Memory first. Adobe recommends 16GB or more for Lightroom Classic, and the AI features want 8GB of dedicated graphics memory on Windows or 16GB of shared memory on a Mac. Puget’s Photoshop guidance is more specific: 16GB for open documents under 500MB with layers counted, 32GB for 500MB to 1GB, 64GB and up above that, and more if Lightroom is open alongside. On a Mac the figure is set at checkout, which is why 24GB is my default in this guide and 32GB or more is the line for 100-megapixel bodies and panorama work.
Per-core speed over core count. Puget’s Photoshop recommendations say the app gains little past roughly eight cores and that architecture matters more than the count. Its March 2026 Lightroom Classic 15.2 analysis found most of the app lightly threaded, with a 20-core Core Ultra 7 265K beating the 24-core 285K on a JPEG export; export and the AI features are the exceptions. That’s the opposite of what I’m used to from Resolve, where I’ll take every GPU core Apple sells. For an Apple buyer it means the base M6 is a legitimate photo chip, and the step to a Pro or Max buys memory capacity and batch speed; the editing itself runs the same.
The GPU does a short list of jobs. Puget calls a supported GPU essential for Photoshop and the differences between cards small; 4GB of graphics memory covers it unless you’ve got several 4K displays attached. Lightroom Classic is different: Denoise, Super Resolution and the AI masks run on the GPU, and the gap between a slow card and a fast one is seconds against minutes. Import isn’t GPU accelerated. On Windows the floor is an RTX card with 8GB; on a Mac the Neural Accelerators in the M5 and M6 GPUs handle the same jobs.
Storage, and where the catalogue lives. The two schools disagree. Puget wants catalogues on a second internal drive and discourages working from external drives; the Mac buying guides tell you to take the small internal drive and put everything on a Thunderbolt SSD. My answer for a Mac splits the difference: the catalogue, its previews and the Photoshop scratch disk stay on the internal SSD, where the small database reads that make the Library module feel fast are quickest, and the original RAW files go external, where Lightroom only reads them when a photo is opened or exported. It’s the same logic as a video machine: project files and cache inside, the heavy media on the fast external. For the external, the OWC Envoy Ultra 2TB is the Thunderbolt 5 drive for the M5 Pro and Studio, and the Samsung T9 2TB is the cheaper USB drive for the minis and the iMac.
The display decides what the edit looks like. Every pick except the iMac shows up without a screen, and a photographer’s monitor needs a P3 or Adobe RGB gamut, a hardware calibration path and a matte or nano-texture surface. The Apple Studio Display at $1,599.99 at Best Buy is the matched panel for a Mac mini; the cheaper and larger options are in my best monitor for the Mac mini guide. Budget the display before the chip upgrade. And keep Lightroom Classic current: Puget documented a DNG export regression in 15.0 that 15.2 mostly fixed, so a slow export deserves a version check before you blame the hardware.
FAQ
How much RAM do I need for Lightroom and Photoshop?
16GB is Adobe’s recommended figure and the floor for the AI features on a Mac. 24GB is my comfortable default for a 24 to 50 megapixel body with both apps open. 32GB or more is the line for 100-megapixel RAW files and big panorama merges. On a Mac, buy the memory at checkout; you can’t add it later.
Is a Mac mini good enough for photo editing?
Yes, and for most photographers it’s the right buy. The Mac mini M6 with 24GB at $1,299 covers a working catalogue from a 45-megapixel camera. Medium format, panorama work and nightly Denoise batches outgrow it, and that’s what the Mac Studio M5 Max is for.
Mac or PC for photo editing?
At the same price the Mac mini wins on memory per dollar, noise and size. A Windows tower wins on upgradability: the Dell Tower takes a faster GPU and more memory in two years, and nothing on the Apple side does. If Denoise and export speed are what you’re buying, a Windows tower with a 5070 Ti and 32GB is the fastest route; under $1,500 the Mac mini is the better machine.
Should my Lightroom catalogue be on an external drive?
No. Keep the catalogue, its previews and the Photoshop scratch disk on the internal SSD and move the original RAW files to the external. The catalogue is a database Lightroom reads constantly in small pieces, and the internal SSD is the fastest path to it; the originals get read once when a photo opens, so a USB or Thunderbolt SSD like the Samsung T9 carries them without slowing the session down.
