Q: Upgraded iPhoto library from a new Mac with Maverick. Now none of the other machines on the network can open the files.  ... Upgraded iPhoto library from a new Mac with Maverick. Now none of the other machines on the network can open the files. Upgraded one of them to Maverick - it "killed the machine" Is there a way to get to photos without buying new machines? more

Storing an iPhoto Library on a network volume is not supported anyway. An iPhoto Library needs to be on locally connected volume, see: iPhoto: Sharing libraries among multiple users
To make your iPhoto library again compatible with your other macs, you could try to downgrade your Mavericks mac again. Restore it to the state before your upgrade. You will need a full Time Machine backup of your mac from before the upgrade.
See: OS X Mavericks: Revert to a previous OS X version
If you revert your Mavericks mac you will also have to downgrade your iPhoto lirary. Restore it from an older backup of the library, or use the paid version of iPhoto Library Manager to downgrade the library.

Oct 29, 2014 2:52 PM in response to léonieby Tedinny,oK - i should have said "networked" drive - and it worked fine across five computers. Problem is that the new machine came with the new software, so reverting - i.e. installing the old operating system - is not an option - at least so said the guys at the Genius Bar. I was told that the only way out of it, unless someone knows of a software fix - is to change out the hard drive for a new high speed drive and increase the Ram - which, they say, will still not restore the performance to what it was before the upgrade. Alternatively, copy the photos into a new library and run two libraries and develop a process to assure they are in synch (good luck). Thanks Apple for not making this backwards compatible - but I guess just like with your new "connectors" and power plug, its a way of forcing new equipment buys.

Usually iPhoto will give a warning, when it is opening an iPhoto library in an older format, that this will make the library incompatible with the older software. You should have stopped at that point. Apple's software is usually able to open older document formats, but there is no way that older software can work with new library formats, that had not been invented, when the older software had been written.
As to your network drive: You really have been lucky that it worked so long: Have you read the document I linked to?
It's recommended that you store your iPhoto library on a locally mounted hard drive. Storing your iPhoto library on a network share can lead to poor performance, data corruption, or data loss. If you use both iPhoto and Aperture with the same library, using a Mac OS X Extended formatted volume is recommended. For more information, see Aperture: Use locally mounted Mac OS X Extended volumes for your Aperture library.

That is really a problem, if you cannot downgrade the new machine and upgrade the older machines. Keeping two separate libraries and syncing them is probably the best option, if you want to use iPhoto on all machines.
