Using the same wallet.dat with each, or have you deleted wallet.dat (after making sure you have a good backup somewhere)?

Bitcoin cannot access files on your system.
Maybe your permissions aren't set right?
Are you using a very old version of wallet.dat?
Your harddrive might be corrupted, in the worst case a mechanical failure is imminent. Do you have backups?

edit: to clarify, Bitcoin can not create a file named "a" in a hidden folder called ".lock". Maybe you dont have write permission for your ~/Library/Application Support directory?

Talk to some of the exchange and pool operators, the leveDB randomly corrupts on more platforms than just MacOSX. This needs to be looked into before 0.9.0. The result is devastating downtime when a full block chain download is required.

I did try it both ways, didn't work, same result.

I am also having trouble with a spontaneously corrupting block chain database but in this case on this brand new Mac Mini the program will not run at all with without an existing blockchain database and wallet.dat. 

Can anyone help?

I do agree that the frequent corrupting of the block chain is a big problem but this is can be mitigated by backing it up frequently, deleting the data dir and replacing it with the backup - then you only need to download a couple of days of transactions.  Definitely not an ideal situation but far better than downloading the whole thing from scratch.

Can anyone help me get up and running again? 

If I just can't use the standard client can anyone recommend the next best one for security?

Thanks.

Didn't see this before posting.

My permissions look OK to me...

Is something wrong?  What should they be?

[manuel]

Ahhh.  FIXED IT.  Thanks.   

.lock was actually a file and not a hidden folder.  Don't know why but deleting it fixed the problem.
