Hi all.

 

I'm in the process of moving from a 10.7.5 iMac to a brand new iMac with 10.8.3.  Using a Time Machine backup.

 

I installed Java Version 7 Update 21 from Oracle (same as had been installed on the "old" iMac.  How come it didn't come over to the new Mac in the backup??? Hmmm...)  (I know!  I know!  it's because I didn't restore system info, just user profile...)

 

Tried launching an app that uses Java and it launched and ran fine.

 

Tried launching TD Ameritrade's Thinkorswim app, which I use extensively every trading day and it gives me a weird msg:

My understanding (Oracle web site) is that you can't have both Java 6 and 7 installed at the same time.

 

However, Oracle also says that Java 6 is dangerous and that it's preferable to install Java 7...

 

So...  What should be the next step???

 

Thanks!
