Thanks all for your feedback. If I can't recover the previous hard drive then I will try this brute force recovery or someone who has experience with recovery.

I tried all 3 options under BIP39

When I create a new wallet using the seed phrase using BIP39 the wallet just comes up empty

Thanks, I will hopefully get the hard drive recovered... I have contacted someone about this.... then hopefully I can double check the 12 word seed, but as I said I was so meticulous about recording it (for fear of such a situation) that I can't see where any discrepancies may be.

I don't currently have access to the old file, it was just on the laptop that got tea spilled on it! I can try and get it recovered... but it doesn't look good. The situation seems hopeless though... is there anyway of contacting Electrum for help with this?... I mean their website just brings me to this forum anyways.

I was extremely careful copying these words down... and looking at the list they aren't really similar to any others.
Can I check does the SegWit Address mean anything. I noted this down as default.wallet originally, does this need to be the same or have any influence on why it isn't working?

Hi,
My previous Mac crashed and I am working on a new one trying to recover my electrum wallet. The process seems straight forward however when I enter my 12 word seed phrase the next button remains greyed out... This wallet was created with newer version of Electrum (i.e. Dec 2020) and all the words are on the list. I have meticulously recorded the 12 word seed phrase and entered properly i.e. lower case, single space, correct order but the next button just stays blank.

I am at a loss what to do it as all the advice relating to this dilemma is just "check the words are spelled correctly" etc. I definitely have recorded it accurately and entered in the right order and should not be BIP39 as it was created with Electrum... so what else can be done?

Thanks
