+======Application Problems======
+===== DaVinci Resolve Performance Issues on macOS Sequoia =====
+====Problem Description ====
+After updating MacBook to macOS Sequoia, DaVinci Resolve runs slowly with high GPU pressure (green portion fills Activity Monitor graph). Simple actions like pressing L to play may take over a minute to respond.
+==== Root Cause ====
+The high green usage in Activity Monitor indicates **GPU (graphics processing) pressure**, which is likely causing DaVinci Resolve slowdowns after the macOS Sequoia update.
+**Why this is happening:**
+  * macOS Sequoia changed how it manages GPU resources
+  * DaVinci Resolve is heavily GPU-dependent for video processing
+  * Your GPU is being overwhelmed or not allocated properly
+  * Sequoia may have different GPU scheduling/memory management
+==== Solutions ====
+=== 1. Check GPU Settings in DaVinci Resolve ===
+  - Go to **DaVinci Resolve → Preferences → Memory and GPU**
+  - Try switching between Metal and OpenCL (if available)
+  - Reduce GPU memory usage slider if it's maxed out
+=== 2. Lower Playback Quality ===
+  - In the viewer, change playback quality from ”Auto” to ”Half” or ”Quarter”
+  - This reduces GPU load during timeline playback
+=== 3. Generate Optimized Media ===
+  - Select clips in Media Pool → right-click → **Generate Optimized Media**
+  - This creates GPU-friendly versions for smoother playback
+=== 4. macOS System Fixes ===
+  - **Restart your Mac** (clears GPU memory)
+  - Check **System Settings → Battery → Options** and disable “Low Power Mode” if on
+  - Close other GPU-intensive apps (Chrome, other video software)
+=== 5. DaVinci Resolve Updates ===
+  - Check if there's a newer version optimized for Sequoia
+  - Blackmagic often releases compatibility updates after major macOS releases
+=== 6. Reset Preferences ===
+  - Hold **Option** while starting DaVinci Resolve to reset preferences
+==== Additional Notes ====
+If these solutions don't help, you might need to wait for a DaVinci Resolve update specifically addressing Sequoia compatibility issues.

-====Cannot move or resize Resolve window====
+=====Cannot move or resize Resolve window=====
 While the program works, it's stuck in one place on one of your screens, it cannot be resized or moved.  Frustrating if you want to make the window bigger or smaller.  For me it was stuck on one monitor the lower left.
