For everyone having issues with Mac; apparently Apple dropped support for 32 bit apps, which I am assuming this is.

I find it kind of irritating that Apple dropped support for that and gives users a generic error message saying to contact developers to update their apps.

You can workaround this by installing a virtual environment and running an older version of Mac. One guide I came across is here:

A Linux/Windows user.

edit: there's also a comment further down where a user reportedly found an alternative solution:

the current version does not work with my mac, can you send me a updated version?


I'm sorry, this needs to be updated to work with mac OS Monterey

have just tried to download the mac version from the website and it seems the link isn't working.

Adobe AIR unfortunately is no longer available on Linux distros, but I'll try out the browser version!

Good luck running the web version since it ran on flash


Wow, perfect for early 90s MS-DOS style music!


this is such an amazing tool


fantastic tool!


This is fantastic. Thank you so much for making this!

Me too...

You can use the online version of it which runs in the browser. Its available in the bosca ceoil website

Online version doesn't work for me, "this site can't be reached"

I can't use this software in the web version and the download version on my Mac too

Hello, I'm excited to use BC but it won't run on my machine. Any chance of an update for Macs running Big Sur?


Same problem on Mac Monteray (latest mac update)


Hey, where can I find the exe file?


it’s in the boscaceoil_win_v2 .zip file extract it first


Hey, peeps - do you wish to partake in a friendly competition between fellow Bosca Ceoil users? Look no further, I created the Bosca Ceoil Arena on Reddit, a small community that I barely started a few days ago. Check it out here:


My M1 Big Sur (11.6) throws “The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.” Any updates?


Wait you are the creator of Bosca Ceoil! That is so cool! I use that to make all music for my games!

I'd love to use this tool, but the Archlinux air package is gone, and thus I can not execute this. I have tried my best - Could you get rid of air maybe?



was really excited to use this but it wont open on mac at all..

Great software!



it's already there

boscaceoil_mac_v2.zip24 MB

it's really useful and super user friendly but sometimes if you tab out of it you can't place anything and the only way to fix it is to stop everything and restart it

Great piece of software!  perfect for beginners (such as my self).

I do have some ideas of what would make better though.

1# ability to import samples to use as instruments.

I feel like this would give music way more variety and make songs sound more interesting. Say, for example, i was trying to make to make some electronic sci-fi esc music, and i wasn't satisfied with the default instruments.  I could create and name a new instrument, and select a sample, such as a short .wav file.

2# plugin support.

add support for community made plugins.

 these are just my  ideas for this once again great program.

Hope you see this, Terry!

can it have plug inns


Can You Please Update The Software For The Newest Mac Version? I Really Like The Software But The Latest Mac Updates Prevent The Software From Being Opened Cause It's Out-Dated And Needs To be Updated. Thank You!


Has anybody found a way to get this to work without Adobe Air? I had it on my old PC and loved creating music with it.


Any chance someone has the AdobeAIRSDK.tbz2 archive for linux saved? Adobe have replaced the link with a blog post.

Go raibh maith agat

It's archived at that address on So it runs but makes no sound now. Okay.


I can't save my project. I name it, I choose where I want to save it, and when I click on the "save" button, nothing happens. Help me !!!!!


Got it working with MacOS 11.2.3 (Big Sur)!

I was able to download the newest Adobe AIR from here: Harman AIR Runtime (from Adobe's blog post regarding Harman taking over AIR development). Download the AIR runtime. Install from the .dmg file.

I then downloaded the Bosca Ceoil V2 Windows or Mac AIR script (boscaceoil_v2_windows_or_mac.air) linked above. I installed the script via AIR.

The first time I ran Bosca Ceoil the GUI looked crazy, lot's of horizontal black lines all over. Quitting and re-running the app got it working fine. Yay!


OMG, this works! I use macOS Catalina and I’ve been searching all over for a way to run it. This is the first one that worked! Thank you!

Worked for me too, thank you, friend!!!!

wonderful program!!  i really enjoy using it because it's intuitive and the instruments are cool..  thank you so much


will there be a version not using adobe air? Adobe air does not work anymore and you cant install it from where you could before, all you get from there is an html page telling you to switch to their new thing :p

Has anyone found a work around for this issue? I would love to get started with this program :)


I have stumbled upon something that works kind of, if I launch directly from WINRAR things seem to work fine...


521 kb for Linux??? why? 

The linux version depends on adobe air, which is the bulk of filesize on mac and windows. See this page for more details!

ok thanks


I'm on mac, using the air version. none of the save/load .ceol or import from .mid buttons do anything. the export button prompts me for a file type, then depending on which export option I choose, a different variety of nothing will happen. if I select .wav, it plays through the song, then it ends, and the play button does nothing. if I instead select .mid, it just stops until I hit play again


Please can we get faster more than 220 BPM?


A bummer you don't update it so mac version actually works :(


Not able to install AdobeAIR, which was discontinued, on Ubuntu.


yep, same issue here, the farthest i got is getting a popup saying it is discontinued... at least the windows version works with wine :)

Oh, I just forgot of Wine. Thanks.


would love to try but there's no stable update for mac :(
