As it pertains to QM17 this issue can not fixed at present.the cash activity shows up under the account transactions and you can see the Account cash balance in the portfolio view but linked cash accounts like your accustomed to working with in QW are not available in QM
Using QM 2017 v 4.5.6 so most current available, although this hasn't changed since earlier Mac versions. It would be so easy if I could designate my Vanguard Federal Money Market Fund as the Cash Balance/Available Cash as per the original post. However, my problem is that I can't figure out any way to manually adjust the bogus Cash Balance/Available Cash value that QM is reporting. I've tried every combination I can think of, but nothing I've found changes the reported CASH BALANCE which is reporting -$271,375.71. I also can't figure out where this number is coming from except that adding this to the Market Value gets me very close to the correct answer. I would ignore it if it didn't make the reported "Market Value" at the top meaningless!I did give up on having QM properly track the values of both the Cash and the Money Market accounts correctly, so I manually adjusted the money market account value to be correct. This I could adjust, but it made no change in the reported CASH BALANCE. If one was linked with the other I would understand, but if they are linked I'm not seeing it.
