JPWGIBSON  No issues whatsoever on my MacBook Pro, MacBook Air, and iMac. Still also running problem free on my PowerBook G4.  
(Version 2.1)

JPWGIBSON  I have been using OnyX for several years on 4 Macs and have had nothing but healthy, consistant, reliable, stable machines as a result. This remains true with SL; the only thing having changed is an increase in OnyX's speed and increase in its functions and options.  
(Version 2.1)

JPWGIBSON  Indeed; it was the wholel "ASAP" that seemed a little over the top - especially considering what the developer charges for this app.  
(Version 3.0.6)

JPWGIBSON  Wow; a little pushy, aren't we? What ever happened to "Please & thanks"?  
(Version 3.0.6)

JPWGIBSON  Check out Skim; it does what you are wanting, and it is free.  
(Version 0.0.6b)

JPWGIBSON  Works fine for me  
(Version 1.9)

JPWGIBSON  Me too!  
(Version 1.9)

JPWGIBSON  Permanent Eraser also overwrites 30 times; and it does this for free.  
(Version 3.6.3)

JPWGIBSON  Did you use the uninstaller that comes in the download? I downloaded 2.1b2, ran the uninstaller that comes with it, then installed 2.1b2, which fixed the problem for me. Was your problem - as was mine - with Parameters?  
(Version 2.1b2)

JPWGIBSON  Uninstalling and reinstalling seems to have solved the problem.  
(Version 2.1b2)

JPWGIBSON  I am no longer able to open Parameters on any of my 3 Macs; I receive the following AppleScript Error:

Can’t set «class butT» "enableASInspector" of «class taVI» "tabMisc" of «class tabV» "tabs" of window "paramPanel" to 0. (-10006)

After which the progress bar hangs, and OnX must be forced quit.  
(Version 2.1b2)

JPWGIBSON  $15.99? Seriously?  
(Version 2.0)

JPWGIBSON  It seems that music has to be chosen one song at a time, in order to be transferred to another computer. On the Help page for the application, specifically the "TuneAid Quick Starting Guide" under step 3, it is stated: Click on "iTunes import" then on "Whole iPod". I do not see any such options. Does anyone else see these? Nor can I select entire folders (playlists/albums), but, as above, I have to select one song at a time.  
(Version 1.2)

JPWGIBSON  Does anyone know how to uninstall this? I can't get it working on my iMac (Intel)  
(Version 2.5)

JPWGIBSON  What I mean is that there does not seem to be any action being taken by the developer against all of the problems that have been posted here. I have been very fond of OnyX for many years, using it on all 3 of my Macs; and then the troubles started a couple of months ago, and there hasn't been any updates subsequently. I certainly don't mean anything disrespectful or disparaging by my comment.  
(Version 1.9.6b1)

JPWGIBSON  R.I.P OnyX. It was good while it lasted.  
(Version 1.9.6b1)

JPWGIBSON  It's slow, it's ugly, it's cumbersome, it's expensive: in short, it's a Microsoft product. Get this slack-jawed piece of poorly-thought-out trash off of your Mac and get a real (and free!)word processor – Neo Office.  
(Version 12.1)

JPWGIBSON  Interestingly, I did an erase and install of Leopard (due to an unrelated matter – I was giving this Mac to my mother for her use, and wanted her to personalize it). Out of curiosity I installed OnyX again after this, and ran what seemed to be the problematic function (LaunchServices). No problems whatsoever were encountered this time.

PowerBook G4 (PowerPC) 1.5 GhZ, 2 GB RAM,

Leopard 10.5.2  
(Version 1.9.4)

JPWGIBSON  Another error message and hangup . . . This occurs when doing "LaunchServices" on a PowerBook G4 running Leopard 10.5.2. The message – this time – (see previous entry) says the following:

""AppleScript Error. Finder got an error: AppleEvent timed out. (-1712).

Any ideas and/or theories?  
(Version 1.9.4b3)

JPWGIBSON  Yes, it is definitely hanging; I let it run before bed last night, only to wake up this morning to find it still running. I was running "Launch Services" on 1.9.4b3 (on a PowerBook G4) when the error message and hang occurred.  
(Version 1.9.4b3)

JPWGIBSON  I got an error message stating:

"AppleScript Error. Finder got an error: Connection is invalid . (–609)"

The program seems also to be hanging.  
(Version 1.9.4b3)
