Picnic is designed to run on two or more Macs on a common local area network (LAN/WLAN).

It offers the ability to create shared folders of files which are automatically and constantly synchronized between all user's accounts using Bonjour.

Files can be edited 'offline' and are sync'ed back to other Picnic users when the bonjour connnection is re-established.

It offers an alternative to classical file server (AFP/Samba) based shared folders or network drives through n-way file syncing.

I purchased a 5-user license of Picnic based on a quick test and reviews on MacUpdate. I have twice in the past week emailed the developers for support. No response... I guess I wasted $120.
Here is the text of my emails.

Hello - I'm a new registered owner of Picnic 1.0.3

My MAJOR problem is as follows.

On my home wired network I have:
PowerMac G4 Dual 1.25GHz, 1.25GB RAM and OS X 10.4.10 (with the SOURCE FOLDER) and
Mac Pro Dual 2.0, 2GB RAM and OSX 10.4.10

I want to share a large folder that has all my downloaded installers - called "OS X" it is about 34GB in size.

The source folder has 509 items in it.

I've left both systems running Picnic overnight, checking the folder contents on a regular basis.

At one point the MacPro copy of the folder got to 420 items and seems to have stuck.

I have rebooted each system and left it for another 12 hours and nothing has changed.

When I look at the MacPro Picnic window it shows "OS X (qb@qbg4)" and the spinning icon in the upper right when I look at the Queue.

When I look at the G4 it has nothing in the upper right.

BOTH Queues are empty. I would have expected to see something in the queues.

BOTH Conflict windows are empty.

What is going wrong here???

I just thought I'd mention that I've emailed the developers several times and they've always gotten back to me -- albeit they do sometimes take weeks to reply.


Well that is NOT encouraging news (that responses take weeks.) I've continued to try to get this app to work and cannot. It frequently goes into a "not responding" mode and I have to force quite.

I think I'll forget the lost money as I prepare to move to 10.5. I cannot imagine this app will be any more stable there.

I think the software is very promising, and - after a few initial stumbles - has been working quite well.

I've been using the last 2 betas again regularly, and have not encountered any problems. I've set up a folder to be shared between my 2 computers, and everything synchronises perfectly, and intuitively.

I think the reason I had troubles in the earlier version was because I used the Picnic folder - created in your home/public folder - as a shared folder. This time I created a separate folder to be shared, and completely ignored the Picnic folder. (I am not sure why it is there in the first place?!)

A manual with some help regarding how to set everything up on first start would be great, but I guess that will be coming once the final version is out.

Up till now, definitively useful for anyone having to share files between several computers.

Ridiculous piece of software.

I test it out on two identical folders on two machines (I made small changes in one folder) to see if it works.

It continually tries to sync automatically and continually gives error messages asking if it should DELETE or RE-GET certain files. Errm, sorry I don't want you to delete anything... so I click RE-GET.

And again it syncs and again gives the same message...and again...and again... ad infinitum.

I forced quited the app and deleted it. Think I'll stick to File Synchronization - costs $15 but it simply works!

Well, after a while longer of experimenting, it's quite buggy still.

When I rebooted one of the sharing computers, Picnic did not recognize the shared folder anymore, showing instead a ".Picnic" folder you were subscribed to. No data was lost, since I found all my files still in the Picnic folder in the Finder.

I deleted everything in the app and started afresh, but I don't quite understand what you actually create when you create a shared folder. No new folders turn up in the finder to be shared, and you can't just drag and drop a folder into Picnic either. When you do, it says you used an invalid name, and then does not allow you to create any new folders until you restart the program.

Okay, the above did not make much sense, sorry. Hard to explain. Let's just leave it at "still buggy".

I won't use it for now but will keep an eye on it, or similar apps - until Leopard comes along, which I understand has automatic folder sharing included.

Well, been trying it out, and works very well till now. Sharing one folder between my 2 Macs via Airport, and whatever I move into the Picnic folder on one Mac, turns up in the Picnic folder on the other Mac.

Too soon to say anything regarding stability etc. but seems to do what it says on the tin.

Like the Window design - fed up with brushed metal at this point -, but still would be nice if one could close the window and let Picnic run in the background, maybe as a menu extra or so. For now, I just hide the application.

Haven't tried to add more folders yet, and also have not tried to move eg. an app's datafile into the shared folder, so it can be assessed by that application on both computers - although that's probably a recipe for disaster...
