my 1P acct to handle it (do you pay for this? I haven't completely researched.
As best I can tell, that involves the subscription model. They make it pretty hard to even find the perpetual price now...
Using 1PW 7, I just changed to iCloud from Dropbox within the month. I'm not using the subscription model, just the old perpetual payment. I assume you are not using the subscription method either since that uses a sync method with 1PW servers (I think).
Another factor in my problems is having an older version on my Mac mini that may have come from the App Store. The newer version on my iMac comes from AgileBits.
I tried to get all three apps to use DB, but I kept getting a request to provide a secret password for the DB folder being used by 1PW! I could not find any such p/w nor was I able to get 1PW to accept my pointing it to my DB folder.
Additionally, the 'Help' files on the 1PW site are a little different depending on which version you might have, IMHO.
I finally took the easy way out and started syncing with iCloud on the old iPad, iPhone and iMac. I am still using version 6.x on the Mac mini and have decided not to worry about updating it, much less to get it synced since it is rarely used to surf. I think I can still get it to sync using the WLAN method, but I have not 'messed' with it in over a week.
I have been able to get help from 1PW Support fairly quickly, however, I suspect they will require a new license to update the Mac mini version and it's just not worth that extra cost!
If all else fails, I know a good wig supplier.
