Someday's I just feel like being redundant. ;)
That is all that the developer's website says about this version.

Version 1.4 seems to be working properly here with /Users on a non-boot volume.

Yes @sjk, as per https://github.com/norio-nomura/EasySIMBL/issues/2

Thanks, ylluminate. I'd only looked at source code changes earlier.

Removed some characters around the error message as the full text is not show:

Cannot find executable for CFBundle 0x7f981187220 /Volumes/..path to home dir not on startup vol../Library/ScriptingAdditions/EasySIMBL.osax (not loaded)

Same trouble here with EasySIMBL (1.3) when /Users is on a separate volume and ~/Library/ScriptingAdditions/EasySIMBL.osax isn't deleted like on systems it works correctly on.

A console message like this is logged if EasySIMBL is launched when ~/Library/ScriptingAdditions/EasySIMBL.osax (with /Users on a different volume) doesn't exist:

SIMBL Agent[246]: linkItemAtPath error:Error Domain=NSCocoaErrorDomain Code=512 "“CodeResources” couldn’t be linked to “_CodeSignature”." UserInfo=0x7ffde520a3a0 … NSUnderlyingError=0x7ffde3c7c850 "The operation couldn’t be completed. Cross-device link"}

Which applications do you mean? The Finder for example is also not in your user library, but it's working.
With another user you just have to start EasySIMBL one time to get it running.

An example would be Safari Cookies. It installs in the SIMBL folder in the Applications Support folder in the System Library. The current product does not take this into account. Since SIMBl bundles can exist in either location the product should take this into account. It also would allow users to move bundles from their user SIMBL folder to the system library so that they would not have to place the bundle in each user SIMBL folder.

Then just move the bundle to
~/Library/Application Support/SIMBL/Plugins

While true, the product still does not address both folders. While your method works for more sophisticated users it might seem daunting for the novice. Also, by using the root library it assumes you want to have all SIMBL bundles available to all users which is not necessarily the case.

Bottom line:The developer should Just fix it to handle both folders or clearly state in your description that it only supports the root SIMBL folder so that users might not be confused.

One of the things that Lion and Mountain Lion bring is sandboxing and as more applications become "10.7 and greater" they have to follow Apple guidelines about it, what means that applications can only write to the user home folder. So the developer is only following guidelines so his app works in the future.

If this is the case then perhaps the developer should consider including an explanation of this for novices, in a manner they can understand it, along with a compiled Applescript to accomplish this.

Many users do not want to upgrade to 10.7+ for software obsolescence reasons or hardware incompatibilities forced on them by Apple which requires them to buy a new machine. My upgrade to 10.8 cost me around $4000 because of this - new Mac Pro, plus additional compatible hardware and software, just to have the same capabilities as I did with 10.7.

About the explanation, yes, he could make it clear in just a few words. About the AppleScript I don't understand... do you mean an AppleScript that moves all your SIMBL plug-ins from the first level Library to the user Library? That could be an option, but you could have better luck proposing the developer that as a new feature than criticizing his software, which is great and free.

Any user that doesn't want to upgrade can continue with his present machine and OS version because nobody is oblige to upgrade. In this case, SIMBL works fine in 10.6 Snow Leopard, so you can keep using it. But when 10.7 came out, SIMBL stopped working and the original developer did not upgrade it anymore. Then EasySIMBL came to live to overcome that problem and adjust to the new developing guidelines imposed by Apple. Why don't you complain to Apple? or to the developer of the original SIMBL?

So, If you don't want to upgrade you can use SIMBL. If you run 10.7 or 10.8 you can use EasySIMBL... and everybody happy.

By the way, if you upgraded to 10.8 spending all that money is because you needed it for something else. If not so, you were the one that made the mistake, because I am sure that no Apple rep forced you to do so.

Come on guys, a developer spends his time, effort and knowledge to create a FREE app that works and you just complain about it when you should say thank you first and then suggest ideas or features to make it better.

To Botacco: You are partially correct. No rep forced me to upgrade but Apple did due to forced obsolesce - just like they did when they dropped the PPC from future upgrades. If I had not spent the money I could not have run some of the programs I use that were also upgraded to run only on 10.8 and would have been stuck in the past. I am not blaming this user, only suggesting that he, unlike Apple should consider the ramifications of making this internal tool, only compatible with 10.8+ and kindly offer some additional tools for novices to handle the details of moving the various files. It would also help him by reducing support requests. FYI: I voluntarily support a number of individuals, and small businesses who have no idea about system internals. So I understand what it is to do something for free.

I don't want to begin a rant war and you are free to think that way, but the world of technology you live in doesn't. Of course I would like that my new machine would last two years being the best kid in the block, but I have come to be happy with it while it does what I need. I still have machines running from 10.4 to 10.6 in production, because they do what I need them to do and they do it fine. But of course I have new machines running the latest versions of the OS and new applications.

You didn't have to upgrade if you had system 10.6 and a version of, say Photoshop, compatible with it. I still have machines running 10.5 with FreeHand 11 and they work fine and as useful as the they they were bought. But if I want to use CS6 of course I need to upgrade my system. This is just an example and no body forced me to upgrade. It was just me that wanted the new software so I had to follow the industry. But if all I want to do is keep working with a tool that is working fine, like FreeHand 11, nobody forces me to upgrade.

Buying a machine and software is an investment and one that looses value each and every day that passes. As a private user most of the time the investment is not worth because it will be obsolete before you can really get the return in value measured as fun and the things you will do with it. But as a private user you buy with your heart and desire, not with the head.

As a professional user or as an SMB, you buy with a budget and thinking that the investment has to make a return in a predefined period of time. If you the outcome is positive then it means that the investment was worth every penny because it made you work better and get more work done. But if the outcome is negative it means that you were wrong buying that machine and software in the first place, because you didn't really need it.

This world is complicated and imperfect. That is why is even more important that we all try to cooperate and get the best out of every situation.

I hope you get the best out of your $4000 system and that it lasts fast and powerful for many years.
