How do customers feel after buying Ruby on Mac?

It really was a life saver, not sure what other option I would have had other than to completely erase my computer start from scratch. That’s something I would not have done, I just would have not build projects and told the devs that I can’t help with testing. Really a dead-end blocker when this stuff doesn’t work.

Having had a Mac for many years, I think my system was clogged by some old configurations and pre M-1 builds. So various projects did not build for me and devs tried to help me but also could not figure it out. I spent many hours trying to understand how it works, but to no avail.

The Ruby on Mac reset did it though and so far things are working smoothly. Thanks for building this helpful tool.

Christoph Ono

Praise God for this tool! Thank you for developing it. This saved us weeks worth of troubleshooting and configuring everything. We may have never been able to figure it all out.

Tom Snide

My setup now starts with Ruby on Mac - it helps to get the machine into a state where I can just go about my day with RVM instead of fighting with the Mac's unfortunate default state. It's a serious time saver with some extra value add nuggets.

Wayne E Seguin

Creator of RVM

My local dev environment had become increasingly sloppy over the years — lots of migrations from computer to computer, permissions issues, etc. I spent a lot of time remedying things on my own, and I am so glad I found Ruby on Mac when I did.

I couldn't be more impressed with the product and am very appreciative of Moncef and the fantastic customer support. Ruby on Mac is well worth it.

Trent Walton

As a new MacOs user, I had already given up on what to do as I couldn't even run flutter. Spent over 3 days trying to figure out how to get ruby to work and why Cocoapods won't even install.

Your RubyOnMac script helped me overcome a major headache and I just can't thank you enough. I am from a low purchasing power country and your discount code helped soften the financial blow to my earnings.

Thank You once again for developing such a wonderful tool.

Lawrence Inyang

Yes, it did work. A co-worker had discovered it. We are both iOS App Developers and recently inherited a very large app to maintain. It used 19 different frameworks all managed by CocoaPods which in turn is based upon Ruby. Though we have the latest Macs and MacOS, the Ruby included by Apple is older than current and that used by the framework developers.

Thankfully, I was able to “reset” my Ruby Stack using your tooling and saved probably a WEEK or more of “headbanging” getting all the dependencies sorted out. The iOS app went from having literally dozens of errors to a clean compile once that was done. Worth every cent.

Don Babcock

THANK YOU. THANK YOU. THANK YOU. I don’t know what to say. The documentation is thorough and this took less than 10 minutes on my Mac. At first I was like, this can’t be that easy.

I was skeptical because I really was trying to brute force a solution prior. I was doing all kinds of things (setting permissions on a folder, install this, install that, etc). I was just thinking that the script probably wouldn’t be able to perform as touted because of how old my files are and all the trial and error I was trying. I’m just so happy that it worked as advertised.

Nathan Boyd

Dude, this rocks. I spent hours trying to get Jekyll to work on my new M2 Mac. Every time I thought I had it something else would break. Your script fixed it in about 10 minutes. Very clear instructions and it just works. Totally worth twice the price, IMO (I bought the $129 option).

All I want to do is write a simple blog with an easy-to-use static site generator. The whole purpose of using an SSG is so I can write _about_ code instead of writing code just to publish a blog post. And WordPress is just obsolete IMO for blogging.

Every single SSG I tried out had some issues. Thankfully your script resolved the Jekyll issues for me. I was skeptical your tool would work so was really pleasantly surprised that it did - perfectly.

Scott Lewis

Web Developer & Blogger,

You saved the day. You deserve every penny of what I paid today. I had an environment using grunt and compass to compile sass and suddenly after MACOS Ventura it ceased to work. I have to say that I was very cynical about the product, mostly if it would work, but it did! All is good now! Thank you!

Luis Alves


Wow, Ruby On Mac FTW! 🔥 If only I could get those 10 hours back from the last few days spent trying to get 2.6.10 installed on this MacBook Air M1. 😅 Now my legacy Rails 5.1.7 / Ruby 2.6.10 app is running nicely and I can begin the process of upgrading to Ruby 2.7.7 🚀

Dan Weaver

Just wanted to thank you for Ruby on Mac even though (or maybe especially since) I am not an engineer. I have not been able to run my portfolio site locally (Jekyll) since we bought an M1 Mac a long, long time ago. Parsing how to figure out wtf was not working and blindly copy/pasting commands into Terminal worked about as well as you expected, but I just purchased Ruby on Mac earlier today and for the first time was able to run my site locally again.

Carolyn Dew

Senior Designer/Researcher, Nava

It totally worked. Thanks Moncef! I bought it because the last time I tried to get Ruby/Rails set up on new MacBook Pro it turned into a headache and I needed a developer to help me get it all done. I didn't want to bug a developer and with your tool I was able to get up-and-running all by myself. Totally worth the money.

Daniel Burka

WOW! This is an excellent product. It resolved all my issues. I've been banging my head against the wall trying to figure this out for hours, and your product resolved everything in minutes. Thanks so much!

Aaron Mateer

So far, the outcome of using the script has been flawless. I've used one of your step-by-step guides in the past to setup an M1 Mac and was very happy with that, was also happy to learn along the way by taking the time and doing everything manually, but this time I didn't really want to take all the effort on my current Mac and I'm getting an M2 MBA in 2 weeks so figured it would be better to get the script and just make all this so much easier and faster.

Judson L Moore

I ran Ruby on Mac and it worked great! It fixed all my stuff immediately.

I know just enough about using the Terminal to be dangerous, and Ruby on Mac has already gotten me out of that danger more times than I can count. I don't understand how Ruby on Mac does what it does, but I am insanely grateful that it does it. Over the past few months, Ruby on Mac has become the utility that does the most regarding something I understand the least.

In a world where BMW owners are gonna pay to have heated seats and heated steering wheels, this was money well spent for me, and I love an app like this.

It was so weird. I had two Mac M1 already and could install Ruby myself. And then I had another one and spent probably 4 hours trying to do exactly same setup as before and it never worked.

And then I just bought your solution and everything worked on the first try!

Anton Podviaznikov

Thanks a lot, running "rom setup unity" and letting unity build to a clean folder made my game build again :) I was really frustrated over this stuff, but now I am super happy that I found rom!!!

Alvar Pernroth

Yes it worked very well. I bought it because without it all version managers failed to install ruby. Great tool!


While I don't run into problems with my ruby environment often, every time I do, getting out of the hole I've dug for myself is slow and frustrating. I'd been trying to fix an issue and clearly made things worse before they were getting better. I spent probably more than an hour before I realized I wanted to clean up the mess and start "fresh".

Ruby on Mac had me back to a clean starting point within 15 minutes and the confidence to move forward again. The documentation and troubleshooting were some of the best I've ever seen for a very technical product. Impressed!

I spent around 3 days trying to solve dependencies and version issues mixed with an M1 mac chip while working on a Rails app. I looked and tried and retried so many possible solutions from so many sources on the web... but nothing was working. Then I clicked on the logo menu of one of the numerous blog posts I read, and I saw exactly the words I was looking for: "Goodbye gem and Ruby installation issues. Hello Ruby on Mac."

At first I thought it was too good to be true, but after a background check, I decided to go for it. And man it worked so well I am ready to dive into my app development again. Thank you again!

Monica Randriamialy

Founder, Nova Pixels

Just a quick note to say thanks! Struggled for a day trying to get the Flutter development stack to work, which has dependency on cocoapods -> ruby which i have absolutely no interest in, but was causing builds to an iOS app to fail.

Your script worked as advertised and 15 minutes later i was deploying to iOS devices.

Robin Puthli

It worked! Thank you for your help! I don't usually like to pay to troubleshoot but this was definitely worth it!!!

Rebecca Krisel

Lecturer, Columbia University, SIPA

The unfathomable and horrible number of hours I would have spent in utter disappointment trying to do this all by myself are goners! And I can resume the Jekyll journey in peace now 😎 Thank you again.

Sarah Choukah

I was having some issues with react native environment setup. I use a M1 macbook and it was too hard to build a react native environment. I tried different versions of react native and ruby with no success. This was before rubyonmac :) The rubyonmac solved 99% of the issues with ruby and cocoapods dependencies. The only thing I had to do was to execute a "bundle install" and "pod install" inside the ios directory of my react native project and I was ready to go.

Marcelo Araújo

When I first purchased Ruby on Mac, it was smooth as silk, installed quickly and easily, no issues at all. I purchased it because I just bought my first apple computer (MacBook Pro) so learn flutter/dart to develop for android/iOS so I’m new to the MacOS. Ruby on Mac seemed like the best solution for getting ruby and having cocoa pods installed plus I felt that I wasn’t “going it alone” because you made it clear that I could address any issues or concerns to you directly, and that’s what made my choice for me. Thank you for building this tool.

David Hilliard

I initially thought Ruby on Mac was expensive, but I wanted to use Ruby to build a site using Jekyll, and I had already spent several hours trying to get it to work, but couldn't. So I bought it, and Ruby on Mac got things working instantly and cleaned up my environment so I could focus on developing.

I love that Ruby on Mac just works, but the main reason I would recommend it to others is Moncef. I had a couple of extra issues due to the mess I've made playing with different Python environments and flags. Moncef even released a new version within 24 hours to help me.

Michael Rogers

I bought Ruby On Mac for all the reasons really that you outlined in the benefits. I have a project that I am doing using Swift and I wanted to use CocoaPods on an M1 Mac. I was able to get it running with rbenv but it still threw up permission errors now and then. I have a short time to complete the work for my Masters degree so I felt this was certainly worth the cost to get the environment up and running and move on with the project. I really love the automation and the clean up with ROM.

Paul Olphert

Yes, it's a great product. I rarely ever leave reviews or provide feedback on products but I really was delighted with the script. I was attempting to build a site with Jekyll and was getting caught in a rat's nest of errors. I wasn't sure what needed to be done to resolve them and stack overflow posts were more confusing than helpful. Thanks!

Liam Quinn

I’ve been banging my head on the wall for hours trying to solve a problem with Ruby on my new M1 mac. I think it was all from an Intel Mac misconfiguration which never bit me before.

I tried your script in normal mode, it failed and told me to run in reset mode. I did and then ran your script again in normal mode. It worked beautifully.

Thanks for making such a great product. Great instructions too.

Richard Stacpoole

This is just a mail to thank you. As a beginner in the development field, I have been struggling for days to install proper ruby and proper rails on my Mac. Thanks to your script, it was all properly set in 10 minutes, this is fantastic!

Inès Fevrier

Yes, it worked! I had a cocoapods project I couldn’t get building on my M1 mac no matter what I did, and this finally solved the issue.

Ben Spees

Everything worked perfectly. As a software developer for 35 years I can say I'm very impressed at what you have been able to put together. It seems pretty much bullet-proof. Bravo!
