Not even close - fake as can be.
Not authentic in my opinion. There is not one characteristic in this signature that would match Michael’s. The forger misspelt ‘Michael’ with ‘Micael’. They missed a ‘H’ in Michael. The signature has too many spaces in-between each letter. There should not be a space between ‘Jac’ and ‘kson’. The ‘M’ is totally off. The ‘J’ is incorrectly formed. etc. etc.
Definitely not real in my opinion.
