I'm a newbie to post but not read and hoping someone a lot smarter than me (which are many) can help with the worrying issues I'm having. I have read several threads and tried to find solutions to no avail and apologies if these have all been answered before, elsewhere.
I am on a Macbook Pro using Sierra.
Issue 1.
1. I mined and bought BTC back in 2014.
2. They were all put into a Multibit Classic Wallet and have remained there until now.
3. I recently downloaded Electrum to move the contents over understanding Multibit is WAY out of date, unsupported and potentially volatile now.
4. When I enter the Electrum 'receiving address' into Multibit it is not recognied as a BTC address. I have read differences and incompatibilities between compressed and uncompressed keys, is this the issue?
5. I have tried to save the private keys from Multibit to my computer, here begins issue 2.
Issue 2.
1. So, from Electrum I decided to try a sweep of keys to bring all into the new wallet.
2. Having theoretically saved the keys from Multibit Classic, the process was confirmed, it gives me a directory where it has been saved on my comptuter 'user/"name"/library/application support/multibit/multibit.wallet'
2. On MY computer 'application support' doesn't exist in this location, it is elsewhere and inside there is no Multibit folder, the ONLY multibit folder I have, or can find, is to launch the program?!?
3. ......Mega Panic sets in.
Issue 3.
1. Having dowloaded Electrum, all seemed ok. setup seed, password, default wallet created.
2. When I shut down Electrum I cannot find the file/folder, computer says 'file doesn't exist'
3. I tried to reopen from the launcher but it prompted going through the whole process again.
4. Back to the absent application support folder I can find nothing on my computer relating to the recent new set up of the Electrum wallet.
Big panic, anyone have any ideas or solution please, I've read a lot, tried a lot and getting confused by all the solutions on offer and not working and of course mega nervous to lose my BTC. The absence of a folder with files, .key docs, etc. seems to be strange.
Cheers!
All Solved Now! Cheers all!
