Photoshop 2022 slowdown on a MacBook usually comes from limited free storage, oversized documents, excessive history states, a troublesome plugin, or graphics settings that your system struggles to handle. A scratch disk error appears when Photoshop cannot use enough drive space for temporary working data.
Work through the fixes below in order. Start with storage and document size before changing preferences. Those steps are quick and solve many performance problems without affecting your editing setup.
Check your MacBook’s available storage
Photoshop uses your Mac’s storage as temporary workspace while you open images, apply filters, create selections, and move between history states. A drive that is nearly full can trigger the message “Scratch disks are full” or make common actions feel unusually slow.
Open the Apple menu, choose System Settings, then select General and Storage. Remove files you no longer need, empty the Bin, and move large video files or archives to another suitable location. Leave enough free space for your normal Photoshop projects instead of filling the drive immediately after cleaning it.
After freeing space, restart the MacBook and open Photoshop again. A restart can also clear temporary system activity that was competing for memory and storage.
Choose a suitable scratch disk
If Photoshop opens, go to Photoshop in the top menu, choose Preferences, and open Scratch Disks. Select a drive with sufficient free space. If more than one drive is available, you can assign another suitable drive as the primary scratch disk and place it first in the list.
Close Photoshop and reopen it after changing this setting. If the scratch disk warning appears before the application fully loads, hold Command and Option while launching Photoshop. This may open the scratch disk selection screen, allowing you to choose another available drive.
Use a drive that your MacBook can access consistently. Avoid selecting a removable drive that may be disconnected while Photoshop is running.
Reduce Photoshop’s memory and history load
Open Photoshop > Preferences > Performance. The Memory Usage setting controls how much available RAM Photoshop can use. If other applications are running at the same time, reduce the amount assigned to Photoshop and close unused applications. If Photoshop is the only demanding application open, its current allocation may be suitable.
History States also affect working memory and scratch disk usage. A very high number lets you step further backward, but it can increase the amount of temporary data Photoshop needs. Lower the value to a practical level for your projects. You can also review the Cache Levels setting. Large, complex files may benefit from a suitable cache setting, while small web graphics may not need the same treatment.
Save your work before making performance changes. Some settings require a restart before you notice the difference.
Clear Photoshop’s temporary data
When a file is open, choose Edit > Purge and select an available option, such as Undo, Clipboard, or All. Purging can release temporary data, but it also removes the related undo history and clipboard contents. Save the document first and use this step only when you no longer need those recovery points.
Large documents can continue using substantial scratch space even after a purge. Close files you are not editing, especially documents with many layers, smart objects, masks, or high-resolution images. A flattened copy can be useful for a final export, though you should keep an editable version when you still need to revise the design.
Test plugins and graphics acceleration
A third-party plugin can cause slow launches, freezes, or sudden crashes after Photoshop starts. Quit Photoshop and reopen it while holding the Shift key. If Photoshop asks whether you want to skip loading optional and third-party plugins, confirm the choice and test the application.
If performance improves, close Photoshop and review your installed plugins. Re-enable them one at a time, testing Photoshop after each change. This helps identify the plugin that is affecting the application without removing every extension at once.
Graphics processing can also affect responsiveness. Open Preferences > Performance and temporarily clear Use Graphics Processor. Restart Photoshop and test zooming, panning, transforms, and brush movement. Some Photoshop features depend on GPU acceleration, so use this as a diagnostic step. If the slowdown disappears, check your MacBook’s graphics and system support before deciding whether to leave the option disabled.
Review large files and demanding tools
A high-resolution document with many layers can be slow even when Photoshop is working correctly. Check the image dimensions, bit depth, number of layers, and embedded assets. Smart objects and adjustment layers are useful for flexible editing, but they can add processing work to every preview or transformation.
Close unused panels and documents, reduce the number of open applications, and save large projects regularly. If a brush feels delayed, lower its size temporarily and test with a simpler brush preset. If zooming or panning is slow, test the same action in a smaller copy of the document. This can show whether the problem comes from the file itself or from Photoshop’s general settings.
Reset Photoshop preferences when problems continue
Damaged or unsuitable preference files can cause repeated errors after storage and plugin checks. Photoshop 2022 includes preference reset options in its settings. Review Preferences > General for the reset option, then restart Photoshop as directed.
You can also quit Photoshop and relaunch it while holding the shortcut used by your installation to reset preferences. Read the confirmation message carefully before accepting, because custom workspace layouts, shortcuts, and other personal settings may be removed. Export or record settings you need before resetting them.
When reinstalling makes sense
Reinstalling should come after you check free storage, scratch disk selection, document size, plugins, GPU settings, and preferences. If Photoshop remains unstable, remove the application through the available Adobe installation process, restart the MacBook, and install the version you intend to use from a legitimate source. Keep copies of your project files and custom assets before changing the installation.

Should you choose Photoshop or another Adobe option?
Your choice depends on the type of work you do and how broadly you need to work across Adobe applications. If you mainly edit photographs, composites, and layered graphics, Photoshop may suit your workflow. If you need access to a wider set of creative applications, you can compare the Creative Cloud All Apps – 12-Month Subscription option. Another listing, Creative Cloud All Apps with one-time activation using your own email ID, may also be relevant to your comparison.
When researching Adobe Photoshop alternatives, compare the tools you actually use, file compatibility, and the level of control you need over layered documents. A different editor may handle a particular workflow well, but moving between applications can affect plugins, templates, and saved files.
FAQ
Why does Photoshop say the scratch disks are full when my Mac still has space?
Photoshop may be assigned to a drive with less usable space than your main storage, or temporary files may be consuming the available room. Check Preferences > Scratch Disks, free storage on the selected drive, and restart Photoshop.
Will purging Photoshop delete my project?
Purge removes selected temporary data such as undo history or clipboard contents. It does not replace the saved document, but you should save first because some recovery steps may no longer be available afterward.
Is Keys-Shop safe for Adobe Photoshop?
Check the specific product page, listed product details, and purchase information before placing an order. For the MacBook-focused listing, use the supplied Photoshop 2022 product page and confirm that the edition matches your intended setup.
