This is a little awkward, since I am writing not for myself but for a student whom I urged to get OmniOutliner. My student, who has a three-year-old MacBook Air running OS 10.9, says she just bought OO version 4 and cannot install it. She says she gets an error message telling her OO requires OS 10.10, which she says she is unable to install.
I don’t know if her laptop has actually reached its natural limits or whether there is something amiss. But the OmniOutliner 4 webpage says OO 4 requires 10.9. Is this no longer true? If the latest OO 4 requires OS 10.10 or higher, is there an earlier version of OO 4, one not requiring OS 10.10, that my student could download?
In distress,
Susan
