MAC OS 13 went out of support from Apple in November so Intuit is not supporting it, this happens every year.
Intuit is offering desktop users to switch to online premium for no extra cost on Fed. There are other widely used online platforms like FreeTaxUSA or TaxAct.
If not able to upgrade your HW/OS and not interested in using an online service then believe your only other option for installed tax software still supported on older Mac OS versions is H&R Block.
