ANONYMOUS  I think you should have tried this app before writing a review.

This application is meant for those of us who may be doing some real processor intensive things... such as rendering 3D animation. There are many times I am doing this, and all of a sudden a client calls and I need to open Photoshop and make a quick change to something. Instead of quitting the animation rendering... I just pause it. this let's me open up Photoshop and make my changes quickly. If I left the rendering running it would take like 5 minutes to open Photoshop. when I am done, I can "Resume" the rendering.

This app is not for "Managing" CPU usage. That is something I would never want to do. Apple manages that just fine on it's own. This is for those times when you simply cannot afford to quit something just to free up cpu. For me, this happens maybe 2-3 times a day.

SESQUIPEDALIAN  The developer is right. This app is not really managing processor resources. Rather, it allows you to completely pause an app, effectively freezing it and liberating all the system resources it was using. Once the app is resumed, it will pick up from where it left off.

I haven't tried Process Wizard, but it sounds like a graphical interface to the command line tool called nice. App_Pauser is a graphical interface to the kill and/or killall command line tools. Different job.

Personally, I won't buy App_Pauser, since I would just pop open Terminal and type in "killall -STOP Photoshop" if I wanted to pause Photoshop, and "killall -CONT Photoshop" when I wanted to resume Photoshop. But for those who aren't comfortable with Terminal and still want the ability to do this, App_Pauser should meet that need.

JIMW  To DEV: First of all I did not write a review. I wrote a comment and tried to make it a constructive comment with ideas to make your product better. If you wish to interpret it as a review, they YOU have a problem. After reading SESQUIPEDALIAN's reply I must say I understand what is going on now and agree with him. However I do feel that Process Wizard while doing it differently will almost accomplish the same thing by raising the desired process to max time and the undesirables to minimum time.

Addition, if I understand SESQUIPEDALIAN's explanation correctly, what the product really does is provide a GUI to a command line instruction. From my perspective $10 seems a bit steep for this 'one trick pony' but not out of line if it had more features such as what i suggested or adding the capability of Process Wizard to it so that a user could either set priorities or pause the activity as desired.

FYI: This is also a comment and only a comment as I feel would be ethically wrong to attempt to write a review on a product I have not tried.

ANONYMOUS  Ah, but do you actually know the name of the process you would type in Terminal. In some cases they are not exactly what the app is named. App_Pauser uses the PID to determine what to pause/resume. Also, It keeps track of the ones which were paused. Doing this in terminal may leave you with no real way of knowing which apps are paused and which are running.

In your case, you may actually have to open up "Activity Monitor" to find the real name, or us the "ps" command to find the PID or process name. This would prove to be more steps than most would desire. This app actually is more of a replacement for "Activity Monitor" or "ps".

ANONYMOUS  There will be minor tweaks to this app very soon, that will take care of international support. I believe this issue is happening because you computer handles numbers in a different format than an English one.

Sorry for the inconvenience.

FARIBORZ  Hello and thank you very much for your prompt answer. Yes I use European number preferences. I'll anxiously wait for a fix. Thank you again and all the best.

ANONYMOUS  No problem... I know that Macs are actually much bigger, it seems, outside the U.S. So anything I can do to make my apps run more smoothly for that audience is a plus.
