macOS Sequoia vs Sonoma — Upgrade or Stay?
macOS Sequoia (15) added Apple Intelligence, iPhone Mirroring, and a refined Window Tiling system. macOS Sonoma (14) was rock-solid. If you're on Sonoma now, should you upgrade — or wait for the next macOS?
⚡ Quick Verdict
Buy Stay on macOS Sonoma 14 if: your Mac is older (2019-2020), you depend on specific older apps, or you can't afford a week of post-update troubleshooting.
Buy Upgrade to macOS Sequoia 15 if: you have an Apple Silicon Mac (M1+), want Apple Intelligence, or use iPhone Mirroring on the daily.
Bottom line: If you have an Apple Silicon Mac (M1+), upgrade. If you have an Intel Mac (2019+), evaluate — Sequoia drops support for some older Intels and runs slower than Sonoma did.

👤 Pick By Use Case
You have an Apple Silicon Mac (M1+)
→ Get Upgrade to Sequoia
Apple Intelligence + iPhone Mirroring are M-only features. Don't miss out.
You have an Intel Mac (2019-2020)
→ Get Stay on Sonoma for now
Sequoia runs slower on Intel + Apple Intelligence isn't available.
You use Logic Pro, Final Cut, Xcode professionally
→ Get Wait 2-3 months after Sequoia release
First-month bugs hurt pro workflows. Update is fine once .3 or .4 ships.
You depend on niche/older apps (legacy hobby software)
→ Get Stay on Sonoma
Older apps may not be Sequoia-compatible. Test in a VM first.
You use iPhone Mirroring constantly
→ Get Upgrade to Sequoia
It's genuinely killer — control your iPhone from Mac without picking it up.
First-time Mac user
→ Get Get a new M-series Mac, comes with Sequoia preinstalled
Don't worry about the upgrade decision; you start fresh.
