MAMP Pro on Yosemite Beta 5

Update: The developers of MAMP recommend the following workaround:

Workaround for the 10.10 Preview 5 bug: Rename the file “envvars” located in into “_envvars”

If you’re running MAMP Pro 3 and you installed Yosemite preview 5, you’ve probably noticed Apache won’t start anymore, with the following error:

dyld: Symbol not found: _iconv
Referenced from: /usr/lib/libmecabra.dylib
Expected in: /Applications/MAMP/Library/lib/libiconv.2.dylib
in /usr/lib/libmecabra.dylib

This is some kind of library error because of an updated library in the newest preview. You can fix this by forcing your own version of libiconv onto your computer, though you have to replace the system default version of libiconv, which in theory could cause bad things to happen – i’ve not noticed anything, but your milage will vary – and you should make sure you’ve got a system backup of everything incase the worst does happen.

Hopefully you’ve already got homebrew installed – if not, grab it from and follow those instructions, then:

1) Allow homebrew to install duplicates of system software: brew tap homebrew/dupes
2) Install libiconv: brew install libiconv
3) Force it to link (replace) the system default: brew link libiconv --force
4) Delete the MAMP version of libiconv:
rm /Applications/MAMP/Library/lib/libiconv.2.dylib

Then everything should start properly.

MAMP Pro under OS X Mavericks

If you’re a developer and you got access to use Mac OS X 10.9 Mavericks earlier this week, you’ll notice that it’s actually mostly a hassle free experience, apart from changes to the code signing and authorisation model that mean non-signed applications can no longer elevate permissions to root level.

Now, this shouldn’t matter to most people – but if you use MAMP Pro, you’ll find this isn’t signed at all, and means it’s unable to get access to write to the important system files. You’ll get an error about not being able to write to /etc/hosts.

I’m sure the next version of MAMP will fix this, but for now, you can self sign the app to give it permission to modify system preferences.

You just need to open keychain access, click on it’s menu bar item “Keychain Access”, then “Certificate Assistant”, and “Create a Certificate”. For Name, enter your name, Identify Type should be kept as Self Signed Root, and Certificate Type should be code signing. You can pretty much click continue on everything else until your certificate.

Finally, open terminal, and run:

codesign -s “Your Name” /Applications/MAMP\ Pro/MAMP\

That’ll sign the application as you and let you execute it.

Obviously, it goes without saying you’re telling your mac you trust any app you sign – so only do this if you’re confident MAMP Pro (or any other app that has issues on Mavericks with this error) is trustworthy.


If you still have issues, that probably means the signing didn’t take properly, you can run: codesign -v /Applications/MAMP\ PRO/MAMP\ -v

Once signed, that should tell you that MAMP is “valid on disk” and it “satisfies its Designated Requirement” – anything else and the signing didn’t work properly and you should try again!

Falling Behind

For the last 5 years, it’s felt very much like Apple was leading the way with mobile operating systems and technology, but in the last 12 months it’s very much going in the direction of Android, and in the last 24 hours, Microsoft’s Windows Phone 8.

The problem is Apple seem to be making very small improvements every year, which while impressive aren’t enough to keep people locked in their ecosystem.

iOS6 brings some very welcome improvements, but if all we know about from WWDC is all they’re planning on bringing to the table this fall, I think it’s time to reassess my commitment to Apple for my mobile phone.

We’ve had the same, almost completely blank, lock screen for years. It shouldn’t need to take an “event” for information to be shown on it, and it’s the same with the grid layout on the home screen – That’s not good enough for a modern phone when Microsoft are producing things like the gorgeous, 100% customisable, live updating, home screen which can contain probably up to 50 pieces of information at a glance.

Let’s hope the iPhone 6 launch event includes a significant overhaul to the at-a-glace view that it seems everyone else but Apple are able to nail at the moment.
