So
...
how do you up grade download and install that it?
Re seed?
Uninstall 1.73 then put in 1.74
is it worth the upgrade or are there bugs?
Just download the latest version for OSX and overwrite the Electrum Mac App under the Applications folderAlso other questions (noob questions but better safe than sorry)
[1]how and where and in what form does electrum store the private keys on the system, or does it work it out every time?
Your private keys are derived from your seed that is kept in the electrum.dat, this seed can be encrypted if you set a password for your wallet. This password will be asked every time you make a payment.[2]does this changes if I encrypt keys?
Answered in the previous question[3]I take it electrum does not use a wallet.dat being deterministic seed or am I wrong
Electrum stores your seed in the electrum.dat, encrypted if you use a password or in plain text if not.[4] Is their any danger running a 1.74, on a win7 virtual parallels installation and a 1.73 on the OSX
None, but it is better to use always the up to date version to avoid older bugs in the client. Your deterministic wallet is synced trough all your computers, because the blockchain is in the cloud.Thanks is advance
[5] If I start a wallet from seed, the wallet will be unecrypted regardless of weather I had encrypted the wallet before?
If you restore from seed and an electrum.dat file is not already in your system, a new wallet file will be created and you¡ll be asked to encrypt it with a password. Remember this password is to encrypt the file in the computer, if you restore from seed on any other computer the file created in that moment need to be encrypted too.
