A bunch of you are on our wave where we’ve been keeping this updated. Summarizes information scattered around the forum along with some of our own additions. Please feel free to add additional information and links below and I’ll keep this post updated now. **1 Smart client opens to a blank screen** See [viewtopic.php?t=13140](http://www.servoy.com/forum/viewtopic.php?t=13140) for a more detailed discussion of this issue. _Fix #1_ Close all open editors and restart Servoy. _Fix #2_ Delete the globals.js.launch files in your workspace: ```auto rm [workspace_directory]/.metadata/.plugins/org.eclipse.debug.core/.launches/* ``` **2 Servoy doesn’t finish starting up** This one is not fun. Either your workspace and/or your Servoy directory have some messed up files in them. _Fix #1: Reset your workspace_ 1 Rename your workspace. IE, add “\_archive” to the end of the name 2 Create a new folder with the same name as your original workspace folder 3 Open Servoy. You should have nothing in your file system at this point. But hey, now it’s opening again! If not, see “Fix #2” 4 Choose “File \> Import… \> General \> Existing projects into workspace” 5 Click “Next” and for “Select root directory” navigate to your archived workspace. 6 Choose the projects you want to import, make sure “Copy projects into workspace” is selected and click “Finish.” You now have all of your projects back. The unfortunate part is that many custom Eclipse settings have to be set back up from scratch again at this point. Like your SVN connections. (An SVN bug is probably the single biggest culprit for this issue though and somewhere on the forum I think Servoy recommends a different versioning system. **TODO: insert link** ). _Fix #2: Reinstall Servoy_ If Servoy doesn’t startup with a blank workspace as described in steps 1 & 2 above, then reinstall Servoy and start at step 4 above to get your files back. **3 “Servoy takes too long to connect to the IDE”** Fairly benign error as you just can’t use the debugger when this happens. Restart. **4 Headless client quits working** This happens everytime you terminate the debugger before a method the headless client triggered is finished. Restart. **5 Crash when hitting a dialogue plugin call with the debugger on** This is a guaranteed crash everytime on a Mac (not sure with windows). 50% of the time it whacks out your SVN information as well (again, likely SVN bug fault). You can either reset your SVN up from scratch or: _Fix_ - delete directory: “\/.metadata/.plugins/org.eclipse.core.resources” - in Eclipse, go to “File-\>Import-\>Existing projects into Workspace” - choose your workspace as root directory and do NOT check “Copy projects into workspace” (they’re already there) **6 Servoy doesn’t finish quitting** This one is messing with us. I moved a big solution up to 5.1.4 to test and soon discovered that with smart client open, Servoy hangs on quit every time. Troy’s been having this same problem with just about every v5 version to date and 5.1.4 solved it on his machine. _head scratch_ I’m on Mac 10.5.8 and I think Troy is on 10.6.x. I have the latest Java update (thanks Apple for the bonus delete character) and Troy doesn’t. _Fix_ - Force quit. (At the point Servoy hangs, Eclipse has already done its workspace cleanup – I haven’t had any adverse consequences yet.) ---

A very nice compilation David, thanks for sharing! When I see the kind of crap you guys are confronted with in developer on Mac OS X, I’m always wondering whether you are brave or simply mad? I mean, it would probably be a lot easier (and less buggy) to develop with Servoy using a Virtual Windows install… For client, I can see the point of having a platform capable of delivering to Mac OS X of course, but for development? ![:roll:]( "Rolling Eyes") ![:!:]( "Exclamation") ![:?:]( "Question") ![:!:]( "Exclamation") ![:shock:]( "Shocked") Maybe the best workaround for various Mac developer hangs would be VMWare or Parallels? ![:twisted:]( "Twisted Evil") ---

Oh man Patrick, Don’t even say that! We started using FoxPro about 15 years ago because at the time they had Mac and Windows versions and we have about a 50-50 mac/pc ratio here. Within a couple years, Microsoft killed the Mac version, and we were stuck with lame solutions for over 10 years. Now, we are just starting to move that old foxpro db to Servoy. If they pulled the plug on the Mac client, I’d ask for a refund! ---

Believe it or not, with this cheat sheet close at hand developing on a Mac is quite smooth…now. With standard Servoy development tasks, I rarely have to pull this out anymore (without SVN, you’d probably never be reading this once you figure out to avoid debugging a dialogue plugin call). Pushing the envelope is when things can get a bit dicey. Usually happens when we’re combining various additional technologies (web client integrations, inline Java libraries, your Browser Suite, etc). Just have to be ready on those days. ---

@Patrick I just would strongly like to say that Mac Developers should have the same treatment as Windows Developers, and of course for that matter, Linux Developers. So I expect from Servoy the same attention in doing their work right for the Mac platform as for other platforms. I really do not have much humour for that topic, as I do not see it as very funny.

> Robert Huber: > I really do not have much humour for that topic, as I do not see it as very funny. I don’t find it particularly funny either, but it’s more to do with Apple’s treatment of Java than Servoy’s treatment of the Mac. As far as I know, there is more specific code related to Mac to workaround various quirks than there is for any other platforms. I can tell you that it’s also the case for the BrowserSuite, and I didn’t find it funny. So what else to do than take it with humor, except perhaps pressing Steve Jobs to finally accept Java as a first class citizen on his platform? ---

I am always wondering what about these long standing Java bugs only existing on Macs? Is this a myth or does a platform specific, long standing bug list exist therefor? I would really prefer facts which help a developer for this specific case. Most problems we have/found with Servoy don’t seem to be related to (Mac) Java bugs, but I may be wrong.

and that is just some kind of threading issue, if you delete that file then there is a little more time at some point creating that file again, and that seems to be the trigger some how. Strange thing is if i fake this extra time, then it doesn’t have that same effect… ---

marc, In my case, I had never to delete that file! I only have to take care, that there are no, global.js tab (window) open in eclipse if that’s true, in my case, the debug client always opens!! if the first start was succesfull, than opening globals.js, has no issue, even when your restart a debug client. So, to keep it short, when I close eclipse, I always, take care of that all tab’s (window) are closed before. than (again, in my case) the debug client always opens fine the first time! ---

I have noticed that what I need to do is as soon as Serclipse has launched and everything is built, launch Debug Client, then you can quit it, do stuff in Serclipse and from then on (in that session) Client will always open. You also need to be careful to make sure Client is not running when you quit Serclipse. Rafi [Next page](https://forum.servoy.com/t/how-to-fixing-various-mac-developer-hangs/12369.md?page=2)
