Games For Mac Os High Sierra Fixed

Choose the version that best fits your platform:

10. Diablo III (Eternal Collection)

Original Issue: Memory leak after 2.7.0 patch caused the game to consume 12GB of RAM. The Fix: Blizzard released a hotfix (v2.7.6) specifically for macOS High Sierra. You must re-download the full installer from the website (the launcher auto-update fails).

Games for macOS High Sierra — fixed

macOS High Sierra (10.13) can still run a solid library of games if you know which titles are compatible and how to fix common issues. This post lists tested games that work well on High Sierra, common problems you may encounter, and step-by-step fixes to get them running smoothly. games for mac os high sierra fixed

Native 64-bit Games (Best performance)

These run without hacks.

Civilization V – Works perfectly. Fix: If crashing, delete ~/Documents/My Games/Sid Meier's Civilization V/Cache
Portal 2 – Native Steam version works. Fix: Use -windowed -noborder in launch options if fullscreen glitches.
Borderlands 2 – Runs great. Fix: Disable PhysX in settings.
Stardew Valley – Flawless.
FTL: Faster Than Light – Flawless.
Undertale – Flawless.
Prison Architect – Works.
Kerbal Space Program (version 1.12 or older) – Works. Fix: Force OpenGL mode: ./KSP.x86_64 -force-glcore
OpenRA (free, open-source Command & Conquer) – Works.

6) Performance fixes (FPS drops, stuttering)

Lower in-game graphics settings (shadows, anti-aliasing, resolution).
Disable background apps (Chrome, Dropbox, cloud sync) to free CPU/RAM.
Use Activity Monitor to identify resource-heavy processes and quit them.
If using discrete GPU toggle, ensure system is using discrete GPU for gaming (on MacBook Pros with integrated+discrete GPUs).
Consider an external GPU (eGPU) if your Mac and enclosure are supported on High Sierra.

2. The Indie Darling: Stardew Valley

Status: Fully Working (Steam/GOG)
Fix Required: None.
Why it works: Because the game uses pixel art and lightweight code, it runs flawlessly on High Sierra. It is a 64-bit app, so it is future-proof if you ever decide to upgrade your OS, but it runs perfectly on 10.13 right now.

Workaround for modern games (does not work well on High Sierra)

High Sierra lacks Metal 2 and Vulkan support. Most "fixes" will fail. Avoid trying to run: Choose the version that best fits your platform:

Cyberpunk 2077
Baldur's Gate 3
Resident Evil Village
New Call of Duty titles

They require macOS 11+ and Metal 2.

4) Unity/Mono crashes — fix Mono framework issues

Ensure the game uses the bundled Mono runtime; if it uses system Mono, consider installing the Mono framework matching the game’s requirements from the official Mono project.
Delete managed cache folders (e.g., /Data/Managed) if corrupted — only after backing up.

Games That Are Still Broken (Avoid These)

Even with fixes, three major titles remain unplayable on High Sierra: Civilization V – Works perfectly

Call of Duty: Modern Warfare (2019/Remastered): Requires AVX2 instructions.
Fortnite (Chapter 5): Epic dropped OpenGL support entirely.
League of Legends: The Vanguard anti-cheat requires macOS 11+ kernel extensions.

Do not waste time trying to fix these. They are hardware-locked.
