FM27 Mac Mods bundles seven mods for Football Manager 27 on the Mac into one installer, with a tick box for each. They come from Jonathan Sidenros (toastonjam12345-sys on GitHub), who has made the code open source. So you pick only the mods you want and leave the rest out. Also, everything runs in the game’s memory, without touching FM’s own files.
What FM27 Mac Mods does
Four mods deal with players, while the other three handle your squad and your scouting. So it is worth going through them one by one before you tick anything.
- Dynamic PA: a player who clearly overperforms in a season can gain 1 to 3 PA points. It weighs his average rating against his position and league, his starts, form, caps and Team of the Week picks.
- Position familiarity: positions a player has not played for three months lose about one point a month. On the other hand, every match in a position gives a chance to improve, and the out-of-possession role counts too.
- CA weighting: the weaker foot and extra positions cost half as much CA. As a result, versatile two-footed players are no longer punished.
- Quarter Stars: CA and PA stars get quarters, such as 3.25 or 4.75, in lists and profiles.
- Quick Pick without U21/U18: Quick Pick and rotations leave out players registered with your youth squads.
- Quick Pick Planner: adds a By Planner option and a youth list to the Quick Pick menu, plus filter ticks.
- Perfect Scouting: tops your club up to 30 scouts with maxed attributes, complete knowledge and long, cheap contracts.
The limits of Dynamic PA
Dynamic PA is the most carefully built mod in the pack. However, it has brakes: only players with 25 or more starts qualify, and the best odds sit between ages 17 and 21. Also, a player can gain at most 3 points a season and 8 in his career. PA never goes above 200 and never drops.
The mod covers every player in the save, not just yours. Then the «FM27 Mods» app in Applications lists each rise, plus a watch list of players close to one. If you would rather not see numbers, there is an option to hide CA and PA.

How the pack works in game
When you launch FM through the Start FM with Mods shortcut, PA rises go straight into the running game. Otherwise, they are written into your newest save after FM closes, with a backup kept. Position familiarity is also written into the save while the game is closed. For that reason, the author suggests setting auto-save to weekly.
CA weighting, on the other hand, only works with the shortcut, because it changes the game in memory. Quarter Stars, meanwhile, learns the star cut-offs as you play and changes nothing in the game. Finally, the code is on GitHub under the GPL-3.0 licence.

Who it is for
It is for anyone playing FM27 on a Mac who misses the mods that usually come out for Windows only. It also suits players who find player development too rigid. If you want to see players’ real CA and PA, our first pick is FMPT Chief Analyst. Also, there are more programs for Mac players in our Mac tools for FM27 and in FM27 Player Export for Mac.
Download FM27 Mac Mods
The version is 1.1, from 14 November 2026, and the ZIP is 1.1 MB. It runs on Mac only, with an Apple chip or Intel and macOS 12 or later, and on FM27 from Steam. Quarter Stars, Quick Pick Planner and Perfect Scouting also need BepInEx for FM27 on Mac, by sptndc.
- First, save your game and quit FM27.
- Then unzip the file, open the «FM27 Mac Mods» folder and double-click
Install.command. If the Mac blocks it, go to System Settings > Privacy & Security and choose «Open Anyway». - If it asks for Apple’s Command Line Tools, install them.
- Next, tick the mods you want (hold Command to pick several) and click Install. Without BepInEx, the installer asks whether FM may load the helper: type
yand press Enter. - Finally, start the game from the Start FM with Mods icon in the Dock, with Steam open. With BepInEx, the first launch can take a few minutes.
Changing or removing mods
Use the mods list in the «FM27 Mods» app or run Install.command again. To remove everything, run Uninstall.command.
Things to watch
The mods were built for one specific FM27 Steam build. So every change checks the original code first and does nothing if the game has been updated; in that case, wait for a new version. Also, Dynamic PA and position familiarity write into your save, so keep a copy before you start. The author says he made the mods with help from AI and tested them by hand on Apple silicon Macs.
Perfect Scouting also shifts the game’s balance a lot, since it hands you 30 perfect scouts. So if you like a challenge, leave that box unticked. Finally, credit also goes to sptndc for BepInEx on Mac, and to tozmoz, whose FMLibreEditor is the basis for Perfect Scouting.
