Premiere Pro issues with macOS Tahoe 26.0

I just upgraded to macOS Tahoe 26.6.2, and I’m running into a similar overload issue. Has this concerned been fixed? This is significantly affecting my use of Premier. Please advise on how to resolve.

Found a fix for this.

[Read fully before executing the fix]

Quit premiere → restart computer → launch premiere while holding option (mac) → check the “reset app preferences” and “clear media cache” boxes → select “continue” to relaunch premiere.

I recommend exporting your keyboard shortcuts (if you use custom ones) before doing this as it will reset them back to the default settings.

To do this go to “Premiere” → “Keyboard Shortcuts” → “Save As” → name your preset → select “okay” to save.

To reinstall the keyboard shortcuts after resetting premiere, go to “Premiere” → “Keyboard Shortcuts” → select the preset from the dropdown menu → click “ok” to save.

Hope this helps someone 🤙

4months later, any update??

can we now update to MacOS Tahoe or it is still not recommended?

CRITICAL Memory Leak: Premiere Pro v26.0 on macOS 26 (Tahoe) - 89GB+ VM_ALLOCATE Exhaustion
 

Summary: I am reporting a severe memory leak in Adobe Premiere Pro 2026 (v26.0.0.72) running on macOS 26.2 (Tahoe). The application progressively consumes all available physical RAM and exhausts swap space until the system becomes unresponsive or forces a hard crash.

This is not a standard "high usage" scenario. System logs confirm that Premiere is allocating untagged virtual memory without releasing it, forcing a SIGKILL or manual termination.

System Specifications:

• Hardware: Mac mini (M4 Pro)

• Memory: 48 GB Unified Memory

• OS: macOS 26.2 (Build 25C56)

• Premiere Pro Version: 26.0.0 (Build 72)

The Issue: While performing standard editing tasks (proxy workflow, no heavy VFX), Premiere Pro's memory footprint expands uncontrollably. In my most recent crash, the application reached 89.14 GB of memory usage on a 48GB machine, forcing the macOS kernel to create an 80 GB Swap file.

Technical Analysis (from sysdiagnose/footprint logs): I have analyzed the footprint-all.txt and JetsamEvent logs generated during the freeze. The culprit is undeniable:

1. Untagged Memory Allocation: The logs show 84 GB categorized as untagged (VM_ALLOCATE). This indicates that the Premiere engine is requesting raw memory pages from the kernel and losing the reference/pointer to release them.

2. Swap Thrashing: The system was forced to swap 80 GB to the SSD to keep the process alive.

3. Kernel Response: The system triggered a vm-compressor-space-shortage Jetsam Event.

Troubleshooting Steps Taken (Issue Persists): To rule out external conflicts, I have performed the following:

• Clean Environment: Removed all third-party Endpoint Security software / Antivirus.

• macOS UI Tweak: Enabled "Reduce Transparency" in System Settings > Accessibility to mitigate potential WindowServer memory overhead. While this slightly lowered system pressure, the specific VM_ALLOCATE leak within Premiere remained unaffected.

• Peripherals: Disconnected all DisplayLink adapters and monitors (suspected WindowServer conflict, but the leak persists purely within the Adobe Premiere Pro process).

• Preferences Reset: Cleared Media Cache and Preferences.

• Memory Limiter: Setting the "RAM reserved for other applications" to a higher value (leaving only 24GB for Premiere) temporarily delays the crash by forcing more aggressive garbage collection, but it does not stop the leak.

Conclusion: There is a fundamental regression in memory management between the Premiere Pro 2026 engine and the macOS Tahoe memory compressor. The application is failing to release VM_ALLOCATE pages.

I am available to provide the full .ips and sysdiagnose logs to the engineering team if required. This is a production-blocking issue.

I have been experiencing the exact same issues since I updated my OS. I have the most up to date version of Premiere and it's been so frustrating to try to work on projects. 

"Aside from general bugs (timeline unresponsive to hitting spacebar/play, shutting down unexpectedly, general lagging)". This is my biggest issue. I'm on Tahoe 26.0.1 and Premier Pro version is 25.5.0 (Build 13). Really annoying since it get unresponsive sometimes up to 30 seconds. I should have waited a month before updating to Tahoe (I normally wait a month or two when a new OS is released). 😞 

Hi Dani,

I am on version 25.5.0, Build 13.

I am also able to use Project panel > Export Media as well. The problem seems to stop when I restart my computer, but then will occur again, maybe an hour or so after using Premiere. I have yet to test it on another project.

Thank you for your help,
