SHMK  This is awesome, easiest way to schedule applications and I don't have to make a big mess in iCal. Thanks

TIMCRAWF  I have been having a problem using cronnix to edit the "system" crontab. I would choose "Open System Crontab", but nothing would happen. I have searched all over and finally found the answer here

almost at the end of the page. The fix is that if the file /etc/crontab does not exist then choosing this menu item does not work. So the fix is to create it. In the terminal type.

sudo touch /etc/crontab

BUEGELFREI  Lovely little interface. My (almost hourly) backup schedule would have made a big mess in (slow) iCal, but CronniX made it fast and neat to set up. Although CronniX doesn't have yet have a functioning "intervals" scheduling tab, this was not a real hindrance. Events can be duplicated with a simple command-D, and a series of new times can be entered in seconds. Additionally, the help file includes a few pertinent Terminal tricks, and an email of thanks to the developer yielded a quick response from Sven with a couple shortcut tricks for my scheduling needs.

It's free, and it gets the job done. Works fine on OSX 10.4.8 on my 2.0 GHz DP G5 PPC.

Those looking for a GUI for rescheduling the system maintenance scripts in Tiger should probably look to the free OnyX.

PROFINITE  As the previous post noted, v3.0.1 does NOT open on my G5 tower running OS 10.4.6.  
(Version 3.0.1)

TOAD  On my 10.4.6 PPC G5 it says "Cannot open as not supported on this architecture"

DRAELREN  From the dev's website:

Is CronniX compatible with OSX 10.4 "Tiger"?

Yes.

But :)

It dawned on me after people started asking about the maintenance tasks that there can be different views on what compatibility means. I guess most people will agree that a program is compatible if it doesn't crash and generally behaves as expected, or as it did before.

Now, from my point of view, CronniX is a program that helps configure crontabs and it still does that on Tiger. I can edit and schedule tasks as before. It is compatible.

Some of you, however, associate the maintenance tasks with cron/CronniX. Lots of people seem to use CronniX to reschedule the maintenance tasks on 10.3 and earlier. But in Tiger Apple has moved the maintenance tasks to a new scheduling system, launchd, and for those people CronniX does not work in the sense anymore that it allows rescheduling of these tasks. From this point of view CronniX is not compatible with Tiger.

DRAELREN  doesn't show any cron jobs in 10.4.6

every night at 3 am i get annoyed by them

MADNIL  Does not work on my PB running Mac OS X 10.4.6.  
(Version 3.0.1)

ANONYMOUS  Nice little program! Use it for launching a birthday reminder program regularly, works fine! Keep up the good work! Thanks to the developer!  
(Version 3.0)

ANONYMOUS  Out of curiosity... does this work at all with OSX 10.4?  
(Version 3.0)

FUNNELLPD  Easy to use, powerful and free.  
(Version 3.0b3)

EL GREKKO  Yeah great. This utility should come bundled with OS X

Tiny suggestion is that perhaps for cron and shell newbies there could be some more pre set path options like the '/usr/bin/open' as it took me a little while to get the right path to run a CL php script. So a few other common path prefixes would be helpful to people.  
(Version 3.0b2)

ANONYMOUS  Use Macaroni, it does all this and more automatically! : )  
(Version 3.0b2)

ANONYMOUS  I have used cronnix for a year or so and I recently upgraded to Cronnix 3.0b1 and then 3.0b2.

After the upgrade I found that these newer version do not display all of the cron jobs that are in my crontab.

I have only have 4 jobs in my user crontab. Editing them from the command line with crontab shows all 4 but cronnix only shows the first one. They all execute normally.

Just FYI as I have for now gone back to using crontab -e to edit/create jobs.  
(Version 3.0b2)

SEAN  Genius!!!!!Thanks & rescpect to the developer!  
(Version 3.0b1)

DAR  Good to see that this is back in development. Beats the heck out of trying to edit a crontab by hand.  
(Version 3.0b1)

JON  I'm gonna wait for non-beta, but I have an older version of cronnix on my computer and life is so much better for it.

i highly recommend this for app for anyone beyond the most basic level of computer user.

keep up the great work cronnix.  
(Version 3.0b1)

AIRWAVE  This is great! I didn't know this kind of stuff was possible! I use it together with Applescript to make iTunes wake me up in the morning. 2 thumbs up for this one!  
(Version 2.1)

KIERAN  Like all good tools .... simple, effective and easy to use. An invaluable little utility for those who want to automate maintenance tasks such as repair of permissions, change the times for the unix daily, weekly and monthly maintenance so that they run in the day time when your mac is actually awake and turned on or great for administrators who want to schedule automatic execution of shell scripts or other programs.  
(Version 2.1)

DO IT  Great tool. I use it to schedule Permissions repair twice daily, and for various other things... Have _you_ repaired your permissions lately?!? Do it now. Or use CronniX and have it done for you while you are eating/sleeping/whatever.  
(Version 2.1)

JOHAN LAMMENS  Excellent tool! Just what's needed for folks like me who can never remember the crontab syntax.   
(Version 2.1)

ANONYMOUS  Makes configuring CRON extremely simple. A very well designed piece of software.  
(Version 2.1)

DAVEB  Nice, simple, robust GUI to cron. It's especially useful to those of us who don't know Unix (yet ).
