 ====Captioning your Movie====
-First, you need a caption file that Resolve can read.  If you use Zoom you may have a VTT or caption file.  For Resolve you need a SRT file.  Two ways to get this SRT file.  (You can also manually enter the captions but I'm not discussing that here.)
+First, you need a caption file that Resolve can read; if you use Zoom you may have a transcript VTT file. (You can also manually enter the captions but I'm not discussing that here.)
 ===Prepare the caption file===
-  - Copy the .vtt file to new file with an .srt extension
+for Resolve version 19+, it's easier than before.
-  - Edit the new .srt file
+  * Optionally remove the names from the captions  (so the caption is “hello world” instead of “John Smith: hello world”). To do this:
-    - Delete the first two lines: the WEBVTT file and the blank line beneath it
+    - Copy the ...transcript.vtt file (to save its original form) to a new file, say XX.vtt.
-    - For each timestamp, replace the period with a comma.
+    - Edit the XX.vtt file and remove the names from the captions
-      * From: 00:00:03.090 (from VTT)
+      * remove names from captions using vim: ''<color #666666>:g/[A-Za-z].*:/s/^.*: ⁄⁄ </color>''
-      * To: 00:00:03,090 (in SRT)
-    - Optionally, you can removed the names from the captions (so the caption is “hello world” instead of “John Smith: hello world”)
-Preparing the file using vim:

-  - remove names from captions: ''<color #666666>:g/[A-Za-z].*:/s/^.*: ⁄⁄ </color>''

-=====Application Problems=====
+======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.
