RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

RHEL7 installed without problems on iMac workstation.

RHEL8 is not installable because the platform is detected as macefi.

That forces the EFI system partition to be formatted as HFS instead vfat.

https://github.com/rhinstaller/anaconda/blob/55492ad6166f2cd7aed0e802bdf5b4875dc20f29/tests/nosetests/pyanaconda_tests/modules/storage/platform_test.py#L240

RHEL8 does not provide hfsplus-tools nor hfsplus kernel module.

Solution: vfat is still a valid FS for the EFI system partition. This works for RHEL7. 

Anaconda should fallback to vfat for RHEL8 on macefi plattform.

Hello thank you for the report. However, Mac installations are not supported on RHEL and I would like to avoid change like this.
